Disc golf is an up and coming sport. It's played just like regular golf, except that you're throwing a frisbee (or disc) into a basket.
You can play at various parks around Knox, Anderson and Hamblen counties. The best part? It's free. All you need is one disc. Of course, you could get hooked like the guys in the Knoxville Disc Golf Club and end up carrying a bag with 20-25 discs!
If you'd like to learn more about disc golf or where you can play it, just go to the Knoxville Disc Golf Club's website and they'll get you started.
