My vote was both, but I actually have a preference.
Because my seats are in Section K, I like afternoon games the best. It's still during the day, but the sun is at our back for the first quarter or so and then it is only hitting the east stands so we're in the shade. Sorry for those of you on the east side, but I do love day games because we have time to PARTY after the game and it's not late. After night games you are usually dead and just want to get home and go to sleep. Also, you don't get the opportunity with night games to watch a lot of other games that day.
