I've done it 3 times, but all back when I used to shoot tournaments. I take that back, I had one a couple years ago. There is a guy that visits the archery and hunting forums on the internet. His name is Field 14. Anyway, he was a competitive world class shooter for years. Seems to me someone mentioned Robin Hoods to him one time. He at that time had ,something rediculous, like 48 of them.
