Yep, seems there will be a new one in Swanzey, NH which is near Milford. Don't know if it is the result of any issues from Merrimac last year though.
Yes, there are two sanctioning bodies which sponsor cook-off. Kansas City Barbecue Assoc. (KCBS) and New England Barbecue Society (NEBS) Go to either site and you will find lots of info on many thing BBQ!
