Six Things You'll Love About Living in Utah

This post was written from the perspective of someone who grew up in the Central Valley of California and moved to Utah. 


1. Awesome Scenery. Let's face it, it's beautiful here. Every day, you wake up and see the sun rising over mountains in the east and then watch it set over mountains in the west. The mountains are so prominent that you become numb to just how special it is; it almost becomes "ho-hum" scenery because you see it every single day. The rest of the state is filled with amazing red rock formations and five national parks that people come from all over the world to see.  We've got it all within a couple hours drive!

2. Few 100° days.  From May to September, people in the San Joaquin Valley are battered by scorching heat. Triple digit heat can be recorded on any day, and it's not considered to be an anomaly until it gets above 110°. After a couple of summers along the Wasatch Front, you'll become a heat wimp and start turning on your air conditioner when temperatures climb into the upper eighties. I'm not saying that it never gets above 100° in Salt Lake but you can nearly always count those days with the fingers on one hand.

3. Mormons. They take a bad wrap from some quarters, but, let's face it: Mormons make Utah the great state that it is. You don't have to be Mormon to live here -- I'm not -- but give the Mormons props for what they've given us. We have a clean state with a low crime rate, built by people who work hard. Utahans have more kids per family than any other state, and that makes it a great place to raise kids.  You can count on tons of family-friendly places, and lots of other kids for your kids to play no matter where you live.

4. The Mountain Time Zone.  Two hours behind Eastern Time, it's perfectly situated so that live events are televised at a convenient hour but don't keep you up until midnight. In California, World Series games begin at 5:07pm, which is too early to get home before the first pitch.  On the east coast, Sunday night football games regularly stretch out to end after midnight, which is too late for fans who have a job.  The Mountain Time Zone is the Goldilocks time zone: not too early, and not too late.

5. Great Air Service. Because we have a Delta hub in Salt Lake we have nonstop service to Europe, Mexico, Canada, and all over the country. The presence of all other major carriers keeps fares reasonable. No more long drives to San Francisco or Los Angeles to get a decent fare. Parking is cheap, too: only $9 per day at the airport and even less at some of the nearby private lots.

6. Outdoors Lifestyles. With incredible mountains so close by, recreation opportunities are everywhere, and lots people who live in Utah avail themselves of those opportunities. Skiing, hiking, snowboarding, snowshoeing, running, hunting, camping, boating, mountain biking, you name it! If it can be done outdoors, Utahns are doing it!

Standard Time is Different than Daylight Time

The official Twitter Account for the NFL on FOX tweeted out the following today:



This game will be played in London, and since the game will be on TV so much earlier than the usual Sunday games, FOX wants to make sure that people know about it so they don't miss it.

The only problem is that, anybody who follows the direction from this tweet literally will turn the game on one hour too late.  The game does not kick off at 9am EST, it kicks off at 9am EDT.  What's the difference?  9am Eastern Standard Time is one hour later than 9am Eastern Daylight Time.

"Daylight" time refers to Daylight Saving Time, the official setting in place across most of North America from the second Sunday in March until the first Sunday in November.  When we observe Daylight Saving Time, we move our clocks forward one hour, which means that the hour that would naturally be 9am becomes 10am. Thus, 9am EST is actually 10am EDT, and anyone tuning in at 9am EST is tuning in at 10am EDT and thus has missed the first hour of the game.

Being a computer guy, there's one more angle:  Eastern Standard Time is defined as UTC-5, which means five hours earlier than GMT (or UTC, the two are synonymous).  Eastern Daylight Time is UTC-4.  For those of us who deal with applications and programs that are time zone aware, this difference matters.

You may think that this is just an academic exercise and that this mistake doesn't matter, but consider this:  there are two states in the United States that do not observe Daylight Saving Time, Arizona and Hawaii. Arizona is in the Mountain Time Zone (UTC-7), which is two hours earlier than Eastern time.  However, during the summer, when most of the country advances the clocks one hour, Arizona remains on Standard time, meaning that it is three earlier in Phoenix than it is in New York during that period.

I live in Utah, which is also on Mountain Time.  Throughout the winter, clocks are the same in Salt Lake City as they are in Phoenix, but when we in Utah spring forward, from MST to MDT, Arizona remains on MST, putting Phoenix on the same time as Los Angeles.  Los Angeles is in the Pacific Time Zone (UTC-8), which becomes PDT during the summer.  PDT is UTC-7, which is identical to MST.  It does matter whether or not you get it right.

My Geographic Extremes - As of October 2014


I love to travel.  Even so, I still haven't managed to get out of North America; the closest I've come is the island of Curaçao, about 25 miles north of the Venezuelan coast.  Interestingly, three of the four compass point extremes are located on islands.

Here are my current geographic extremes:

Sloppy, sloppy

When I was young, I had complete respect for journalism. I thought that journalists were very careful to get the facts straight and use correct grammar, and, in those rare occasions when they weren't careful, I believed that there were editors who would step in and fix the problems before the stories went to publication.

I don't know whether I was wrong in the past or if things have changed in more recent times, but I keep seeing stories written with really sloppy writing and bad facts. Rather than shake my head and ignore them, I think I'd rather shake my head and then post them here.


I'll start it off with this one-paragraph blurb from CBS MarketWatch talking about some problems at LAX Airport.  The problem this story is in the time conversion. The text says that the halt in flights began at 2:20 pm "local time," which in Los Angeles would be Pacific time, but the writer then converts that time to 11:20 am Eastern.  Yes there is a three-hour time difference between Los Angeles and Eastern time, but Eastern time is three hours later than Pacific time. At 2:20 pm in Los Angeles, it 5:20 pm on the East Coast; it's 11:20 am in Honolulu (at least during the summer).

Maybe this seems ticky-tacky, but this time conversion is not a complicated fact.  The story is just sloppy.

Airfares Make No Sense

Look at the following screenshot


This is a search for a one-way flight from Salt Lake City to Sacramento on Friday, June 6, 2014.   There are four non-stop flights on the route, although I'm showing only two of them in the screenshot, and all four of them are $500 for the one-way flight.

Now, examine the next screenshot, which depicts a search for a roundtrip flight on the same route:


The flights on the outbound portion of the roundtrip itinerary are precisely the same flights that are shown in the one-way search above, but, by flying rountrip, these flights are $126 cheaper than the one-way.

The lesson here is obvious:  If you need to fly one-way on this date, buy a roundtrip ticket and throw away the return portion of the trip.  You'll get your one-way trip for $374 instead of $500.

One Stock's Unbalanced Sway over the Dow Jones Industrial Average. (Not every stock in the average is average)

On Friday, April 25, 2014, the Dow Jones Industrial Average fell 140 points.  In this era of large market swings, that's no longer considered to be a huge move, but it's enough to draw notice.



The interesting thing about that big decline is that nearly half of the movement on that day can be attributed to a drop in just one of the thirty stocks which comprise the average, VISA (V). In fact, on that day, eight of the stocks in the average, more than one quarter of them, actually increased in price, and the aggregate price changes of the other 29 companies would have caused the Dow to drop by only 73 points. VISA made the difference between just a run-of-the-mill down day and the perception of a bad day.

How can that be? How can one stock have such a huge impact on the average, the benchmark that most news outlets use as their benchmark for the entire market?

The answer lies in the way that the average is calculated. The Dow Jones Industrial Average is a simple average. It is not weighted for prices or market capitalization like the NASDAQ average is. The simple calculation methodology means that equal percentage moves in various stocks have disparate impact on the average, based on the price of the stock, which we'll see in a moment.

First, let's look at how the average is calculated. Back in 1896, when Charles Dow created the average which still bears his name, he simply added up the prices of thirty large industrial stocks of the era and then divided by thirty. It is exactly the way we all learned to calculate averages in elementary school (statisticians call this an "arithmetic mean."), and it had the same flaws when Dow first published it as it does today, that more expensive stocks impact movement in the average more than cheaper securities do, but, again, we'll get to that in a moment.

While Dow started out dividing by thirty, as time passed, that divisor had to change. In order to maintain consistency of the number for comparability over time the divisor had to be adjusted to allow for things like stock splits and changing of component stocks in the average. For example, say that one of the companies in Dow's original list underwent a four-for-one stock split, reducing its share price from $120 to $30. This would cause the sum of the prices of the thirty stocks to be $90 less than it was pre-split. If Dow had continued to divide the sum of the prices of his stocks by 30 was maintained, then his average would have fallen by three points even though no wealth been lost by any investor. In order to make sure that values from Dow's average were comparable from one day to the next, he had adjust the divisor, in this example, from 30 down to 28.8 in order to make sure that his average was consistent.

In a similar manner, changes in the company composition of the average also caused the divisor to change. Replace a low-priced company with a more expensive company, and the divisor must be increased; replace an expensive stock with a cheaper one, and the divisor decreases. Over the past 100 years, the predominant trend of the changes has been to decrease the divisor, mostly due to stock splits, to the point that the divisor eventually (in 1986) fell to near one, and then declined below it. The current divisor, as of April 25, 2014, is 0.155715905, which means that every one dollar change in any of the Dow Stocks cause the average to move by 6.42 points (1 / 0.155715905).

And that's how we get the imbalance. Take a look at the thirty stocks which currently comprise the DJIA, along with their closing prices on April 25 and the day's change for each, represented in terms of dollars and a percentage:

AXP American Express Co 87.03 -0.38 -0.4366%

XOM Exxon Mobil Corp 100.41 0.40 0.3984%
2547.74 -21.83 -0.8568%


Note that VISA is the most expensive stock in the list, nearly $200 per share (three years ago, I owned VISA, and sold it for $88 per share when I got spooked, but that's another story).  VISA shares declined over $10, which was over 5% of VISA's value.  That $10.47 change, when divided by the current Dow divisor, means that this stock had an impact on the average of -67.24 points.

Now, say for example that Cisco Systems (CSCO) had suffered a decline of the same magnitude as VISA's plummet.  Cisco's stock would have fallen $1.23, from its opening price of 23.33 down to $22.10.  But, the same divisor calculation means that the Dow Jones average would have fallen only 7.89 points.  Cisco's shareholders would have endured a financial loss of 5.26% in the value of value of their position, identical to the pain suffered by VISA's shareholders on Friday, but Cisco's pain would have barely dented the Dow Jones average.

Today was a very blessed day.

First, we were fortunate to experience the review of nearly 900 new sailors after completion of their hellish basic training. It was truly inspiring to see a room full of young people, every one of whom appears to be much more focused and determined than I was at that age. The ceremony itself was beyond moving, packed with patriotism, the traditions of our 225 year old Navy, and disciplined sailors who were just kids when they began back in July, but who are now ready to serve and defend us.

As the review ended, there was a mad scramble inside that cavernous drill hall as families and sailors rushed toward each other. I found Patrick very quickly and wrapped my arms around him to deliver the biggest hug I've ever given him. Then we found MaryKay, who temporarily had been lost in the crush, and she held her baby boy like she would never let go.

Tomorrow, Patrick flies to Pensacola to continue his journey, but today we were rewarded with eight hours of time to spend with our son. It was the first time to enjoy his company since he was inducted and likely will be the only opportunity until next spring. It was so impressive to see how much he has grown and the incredible maturity he displays. Truly, God has blessed us with a very special young man!

We attended a baseball game in a stadium we've always wanted to visit, swapping stories and catching up on all that has transpired over the past two months. Patrick wore his Navy whites, and all afternoon, everywhere we went, at Wrigley Field, along the street, even while riding the Ell, strangers and passersby came up and said "Thank you for your service." It happened at least a hundred times over the course of those eight hours.

As the afternoon waned, we delivered him back to the base, and he showed us around some of the places on that installation that he has called home for the past nine weeks. Afterward came the toughest part of the whole trip as Patrick's liberty came to an end, and we were forced to exchange goodbyes once again. I gave Patrick another bear hug, and then MaryKay wrapped her arms around him while holding back her tears. Afterward, he walked away to find his mates and return to his barracks, and we got in the car and left the base.

I'm not always emotional, but this day has been one of the most uplifting days of my entire life! I was giddy with anticipation (dare I say "teary?") as I watched the units march into the drill hall this morning. I was overcome with joy when I finally got to hold him. I was beyond proud as I marvelled at what a great young man he is. I'll admit that it was tough to say goodbye tonight, but having him for an afternoon and having to say goodbye was preferable to not seeing him at all. My little boy is a man.


It was a very blessed day.
