LARNED — The practice of firing an anvil into the air with gunpowder is a favorite at the Santa Fe Trail Tired Iron Show.For anvil shooting the best part of the tradition is a huge Ka-bloom made with a base anvil (used by blacksmiths) weighing 126 pounds, a “shooters anvil” weighing 104 pounds, a half pound of black gunpowder, and a high tech sealant — peanut butter!A fuse is lit and the flyer rockets more than 150 feet into the air, accompanied by a thunderous smoky blast of the black powder. Larry and Melody Freeman are the demonstrators. These enthusiasts have taken this family tradition to area and national championships.
