I live in Iowa and there are really only KCBS events here. Additionally there are probably over a hundred KCBS sanctioned events in the states surrounding Iowa, taking up probably every weekend from March to November. So I guess for me it is a matter of convenience, attending as many contests as feasible closest to our homebase to reduce transportation costs. If all the sudden the "Inter-Galactic BBQ Association" starting sanctioning events in and around central Iowa, I would probably attend those as well.
