Teach a friend to shoot.
A couple weeks ago, the most satisfying feeling I had was when I helped one of my shootin buddies figure out that he was a left-eye dominant right-hand shooter. Armed with that bit of information, he went immediately from his years of embarassing inaccuracy to hitting a 150yd target at the 1" 'x', a feat he wouldn't of dreamed of only one night before.
Now, my wife wants in to the game (since 9-11). I'm speed-reading my copy of "How To Shoot", by Larry Koller, so I can hand it to her this afternoon and tell her to read it before we go shooting.
So grab you a couple of fence-sitters and hand them a gun - sometime, you might be glad to have them fighting by your side.
