Just thought I would throw in here when in KY and you're looking for Barrel char Barton's has it. They also have bung plugs I picked up both for a friend of mine and he says the plugs smoke better as you have to soak them in water first. He uses both together. He gave me some pulled pork he did with it but I haven't tried it yet.
A buddy hooked me up with both as well. Haven't used them yet.
