That map is SOOO erroneously incorrect, it's amusing. There are 4 states who are what I refer to as "non-dumb"... well, three... because one regressed into stupidity. The smart states are Hawaii, Arizona, and Delaware. I forget if it was Illinois or Indiana that was smart for a few years... it doesn't matter, though because I heard they switched back.
Life is so less confusing without having to remember to change your clocks. You silly state people have to go and confuse people like me by switching your clocks... so I think I'm in two time zones instead of one because half the year I'm on the same time as the states to my east and half the year it's the same time as the states to my right.
Besides, with the invention of electricity, do we really need "daylight savings"?
