I actually don't mind the time change twice a year. I make it a fun event to change all the clocks in my home - and I have quite a few of them, one an 1878 Ansonia School Clock. I certainly don't experience sleep deprivation [from the time change]. That said, I enjoyed not having to do it when I worked and lived in Arizona at the beginning of this century. Like Lynn, I prefer the extra hour of daylight at the end of the day, so if I were to choose one or the other it would be full-time PDT (or MST).
