For those who want to know more about it:
Fly Fishing is about throwing "lures" that look more like the real bugs (or baitfish) that a fish would look at. Rather than using the weight of the lure to pull the line out, you have to use the weight of the line to bring out your nearly weightless fly. Flies are made with fibers, feathers, fur and thread tied onto a hook. They sometimes look so much like the real thing, but often they're just big, fuzzy and ugly and catch loads of fish!
The best part of fly fishing is the fight, you can pull a fish in by gripping the line in your hands and fighting that fish's every move. (of course, you can use your reel, too)
