I think this is probly the best idea. I know some of you guys are excited about this idea and I think it's a good idea too, but the way things work with planning tournaments you really need to have this kind of stuff in the schedule a good time in advance if you expect everyone to show up and fish. A side pot at Los Banos would be a great idea because that tournament has alreay been on the schedule, people have made the plans to be there and the turn out should be good. If people don't show up, no loss because they just don't put their $$ in the side pot that morning.
As far as the actual pot goes and how it is paid out, you guys figure that part out, but if it happens, I'll get in on whichever side. I'm 21 fyi.
