I shot competition for 20 years. Only reason I stopped is because I can't walk a full ciruit of the range any more. If you consistently shoot with folks who are better shots than you, you can learn more about shooting a bow in one season of 3D - NFAA field archery is even better - than you can in 20 years of farting around on your own. And make a lot of good friends doing it.
Indoor shooting? I agree with ya. I'd rather floss GMMAT's cats teeth. Two things should never have a roof over them. Football and archery.
