Our schools also have a "mixed bag" of floors. One school has two gyms - the little one is the gymacafeteria tile floor where kids slip and slide all over the place. The larger one has a nice wooden floor they seem to always want to refinish mid-season. Go figure.
Last night our games were at a school with one of those carpeted floors where the bounce is muted and if you turn wrong you can catch a toe and go down.
