DST is a joke and nothing more than a mind game.
The idiots in Indiana finally got it passed into law a couple years ago on the premise that it would solve the problem all the other states were having when doing business with companies in Indiana because they couldn't figure out what time they were on. What did they get... a state that now has part of it on EST and part on CST! Way to go... solved a lot of problems there... now you can go from one county to the next and be in a different time zone.
And they recently did a study on the "savings" of DST in Indiana... and the conclusion was... it actually cost more money because people are home during some of the warmest hours of the day, running the AC and other thing.
Personally, I think DST sucks. If I want an "extra" hour of daylight in the afternoon, I'll go into work an hour earlier. And at least that way when I go to bed at 10:00 at night it will be dark.
