Ann Arbor has its very own Whirly Ball center! This game looks like a blast. It's basketball, but played while riding around in a bumper car. This sport is proof in action that exercise doesn't have to be boring, it can be a ton of fun. The library has all sorts of books on funky sports, including Jump Rope!, The Complete Idiots Guide to Pro Wrestling, and Boomerangs; How to Make and Throw Them.
