Further research has been shown that beer cans work best and of those Moosehead Dry Ice and Keiths IPA work best. A Guiness or two in the stack also improves the air flow. Bud is pure shit and gums up the works. Problem is that those cans have to be empty before they are of use. I would be more than happy to help my Mudcatter friends with the tideous job of empting them and would be more than willing to bring a guitar along and jam to relieve the boredom of preparation.
