The crusties stand and cheer far more often and louder than the folks sitting down low on the players' side of the court. (Excluding the grad students and opposing team's fans). I miss the days when it was all students down there, it can be depressing to look at that crowd and wonder how those people can be so close to the action and not get excited. As for the upstairs bunch, that's where I've seen 99% of my games from. They don't cheer as often as the students, but they cheer loudly lots and do plenty of standing up. During really good games it can be a great workout session.
