Terrell is coming up in a few weeks. It will be an ICBA sanctioned event. I haven't competed there, but they tell me it is a great cook-off. There will be bands and whatnot. They are expecting at least 70 teams. I think that 60 pits have pre-registered. Here is the link to the entry form giving some details of the event. Prize money looks to be $5000.
