There are always cheaters on the 3D courses, it is hard to beat the pencil sometimes. However, I was in an in-door league a few years back. It was teams of 3 guys, mostly for fun. A team member and I always use to beat a soda, just to add a little fun between us. He normally beat me, but one night I was shooting my butt off and shot a 416 out of 420. I knew I had him on this night, but when I told him what my final score was, he informed me he shot a 418. I thought this was funny, because I knew he had shot 8's on his first two targets. After he left, I took a look at his score card and seen that he shot not two, but four 8's, but scratched out three of them and marked 10's. I thought it was funny that this guy had to cheat to win a $1.00 soda. Like you said, there will always be someone out there.
