What if you want to play tennis, but you're sitting in a chair?
No problem. There are many wheelchair tennis tournaments; and there are chairs made especially for tennis. Check out Wheelcair Tennis and see if it's for you.
And what about pool? The National Wheelchair Poolplayers Association says it can be done. And pool is played in air conditioned rooms!
If you want to do something, somebody else probably wants to do it, too. Maybe somebody else is already doing it, just waiting for you to join in. Have fun!
