Just caught a few minutes of Anvil Shooting on CMT (Small Town Secrets ?).  Pretty darn neat ! 2# BP max, 100# anvil min.  They were getting 75' +, straight up. Nearly as good as the launch, was the landing.  Big base  (Steel?) with a cup in the top to hold the BP. They machine the bottom of the anvil and butter the joint with peanut butter ( or PlayDoh ). Complete with spectators. Any sport with 2# of BP and a 100# anvil has to be fun to watch.  Just thought I'd bring it up, before I forgot (right). Enjoy, MIKE
