Tommy, the fraternities actually could not make a buggy exception to add people the the roster and they do not really make their own rules for membership. The basic rules come down from National organizations and/or IFC. There is no way to have two levels of "brotherhood" that would be kosher with IFC or any house's National. And, you missed my point that I wouldn't want to see the fraternities simply allowed to bring in "ringers" of their own. I think that the independents should have to play by the same rules, that's all. If having an even playing field rules wise would keep some students from participating, presumably because they don't want to come out until three weeks before the race, maybe they could participate in some expanded exhibition.
Carl, I think it would be hard to set rules for overall organization involvement, but maybe pushers could be required to have some minimum number of freeroll appearances, just like drivers. Also, do all members of SDC actually live in the dorms all four years? Can they have grad student members then, since no grad students live in the dorms?
Revo, I brought this up again because I think it's worth considering, especially given the recent results.
