From my office I can see that the big stadium lights have been burning all day long at the Durham Bulls Athletic Park. Seems wasteful, not to mention annoying-- since I'm running around putting expensive compact fluorescents in all my fixtures at home. If someone knows where the switch is over there, I'll gladly go turn them off for cryin' out loud.
Is there a reason, maybe similar to the reason why the astroturf at Duke has to be watered (even in a drought) that the stadium lights at the DBAP have to be on (even during the daytime)?
Distant and extremely low-res cell phone pics but even so you can see the huge white glare of 2 of the lights on a sunny day:
