I tried paper and shingles on my still too. It didn't work out so good.
I still think you should lobby for hosting NHC '13. Theme - "Beer & Volcanoes Are HOT!"
I plan to add a good bit of insulation between my hood, and the ceiling, so I don't have to worry about the shingles. And yeah, I think I am gonna try an host NHC. Who might a brewer contact about that? I think I could comfortably fit 6 guys in here. Five if a couple of them were really fat. Once I get the deck on this summer, I should be able to hold eight, or even ten!! Bring it on!
