People are funny. Sure at a club show people always vote for their buddies thats a given(but this doesn't sound like a club show). But who cares??? People get so bent out of shape over trophies.
I just go to check out some cool cars, steal some ideas and leave ha. And as for trophies... i hate the people that put them in front of their car, its just....lame. My few from car shows are collecting dust in my garage lol. And 2 of them are ladies choice

. Back to your point though, I'd just try to ignore that. You run a show that pulled in 200 CARS!!! Thats a great turnout for something local.
