Scavenge Old Tennis Balls

If you need tennis balls for purposes other than playing tennis (for your dog, to put in the dryer, to put on the legs of furniture, put on a walker, etc.) you can sometimes find old tennis balls by scouting your local tennis courts. Frequently tennis players will be playing with lots of balls and may overlook a few around the edges of the court when they pick them up. Also sometimes if a ball is too old for them to play with (has lost its bounce, has a crack, etc.) they will just leave it at the court.
