I'm KCBS certified, as is a lot of other folks here. It's a slightly different ball game then MIM, more meats, garnish and no entertaining of judges. One of the nice things about getting cert'd was meeting a bunch of other yankees that are serious about BBQ.
And Chad is right - getting the team together is the hardest part. Hang out at a couple of comps and see who you meet up with. I met Phil and Gred at one and wond up cooking with Phil and Dave in New Jersey.
