"I can't find much on the Tin Can Round, except that for one target you had to stand on one leg, string your bow, then take the shot. Nubbie...only having one leg, had no problem with that. *^). Wade Phillips may know more about it...the man is an archery encyclopedia. I've read many of the old Ye Sylvan Archer mags and Archery, but don't recall the details of the shoot."
