There would need to be A LOT more promotion and fan support in the West. Senior corps is rather unknown and the stereotype is that of standstill alumni corps or super-mega-old-school.
I went to one of the recent So. CA shows that had the 3 senior corps and 10 junior corps, none of which were top-12 Div 1. Despite being in the 2nd largest city, my family and I literally bought tickets ($10) when we got to the show late, sat mid-way up the bleachers on the 50, and had 2 empty rows in front and behind us for the entire show. There was no one sitting outside the 35 yard lines at all. In contrast, the show with SCV, BD, and BK just a couple weeks before was in a much larger stadium and was packed, with tickets at $22-30.
So what I'm saying is the scene needs to improve, at least in LA, to host a DCA show and be able to pay for travel, judges, etc.
