My herfs are not epic in any sense, but we have fun and, so far, no one has died.
We do the herfs as a pot luck. Tradition has it that I smoke a brisket and do little else except harass people. If they want something else to eat or anything besides water to drink, it has to be brought (oh yeah, and they better bring chairs too). Everyone has gotten pretty comfortable taking over my kitchen, which is a good thing.
A relaxed atmosphere, good people and good sticks are all it takes, IMO.
Of course, it helps to have one of these in your backyard to aid in the atmosphere, but what do I know...
