I think they only run DST through the summer because they know, during this time of the year, there's really no good reason to make the days appear longer. I mean, sheesh, even the bears are smart enough to stay at home right now.
While I dislike seeing the sun set so early, I'm nonetheless always pleased when the DST time of year passes. Even though I live in Michigan, I'm only about 20 miles from the Indiana border, where I do much of my shopping, and less than a hundred miles from Illinois, where they switch to a different time zone. And Indiana, like Arizona, apparently thinks they have enough daylight and feel no need to save any during the summer. It's bad enough trying to remember what time a particular store closes without also having to remember which clock they're using, too.
