A kubb circuit has crossed my mind as well. I think we do Team points.
We could score points based on the number of match wins. Since we play best of 3 in a game. Each win could count as a point.
I think a entry fee is ok
Maybe each region North (MN), West (IA), Central (WI EC), East (WI FV), South WI (MA) holds scheduled matches for a 'season' with a different city hosting the playoffs/championship... A thought
