Its being held on the USS Intrepid in NYC. Not 100% sure of all the teams but I know 3 Eyz, Iowa Smokey Ds, Queology, Pork N' Mindy, Sweet Swine O Mine, Pellet Envy and Cool Smoke are there.
I know smokers purgatory has a Yoder pellet and they were in it last year. Not sure if they used it though.
I bet they can just make a bed of charcoal and run wood on top. But I could be wrong.
