What you also need to look at is what time it would get light in the morning, if not for DST. Personally, I'm glad dawn doesn't show up at 4am in mid-summer, 5 is early enough, thank you very much. On the other side of that, if the sun didn't come up until after 8am at the end of the year, I can promise you Paxil (and other anti-depressants) sales would skyrocket.
The places where it is most notable are the extreme western limits of time zones. That is why Arizona doesn't use DST. If they did, it would be light at 11 o'clock. Same with Indiana, who I believe just adopted DST last year -- not sure why??? It was probably so that people in Ohio would know what time it was in Indiana. Before last year, Indiana and Ohio were the same time in the winter, but off by an hour in the summer. :confused2:
