It's nothing new. Back in the 80's - the days of brass pins and painted balls, for you young whippersnappers - some dingwad at a field archery tournament took a pair of pliers and bent my 20 pin just enough to throw me out of the 10 ring. Never did find out for true who dunnit, but I'm pretty certain of my suspicion.

Aussie, if you're absolutely sure who it is, please PM the guy's name to me. I'll make sure he never shoots at our club.
