There is a first to everthing.

Couple of schools in my area have carpeted floors. My knees started hurting as soon as I walked on the court

The game does seem "quieter" because of the lack of noise coming from the players. Just don't fall while you're running or you will feel it in the morning :P

Don't even get me started about a waffle court that I once had a game on.... (worst surface ever)
