Re: SI
Well, pick your poison. No one can just pick arbitrary times because they'll have to coordinate with everyone else: many of which are "locked in". When you get "oop north" in the winter, there just isn't enough daylight to go around, so you have to make a decision: favor it earlier so kids don't go to school in the dark (safety risks and concerned parents) or favor it later so people are more in a position to enjoy it (psychological issues).
