helmets are painted in the stadium and stored in the Gug, there'd be no reason to put them in a truck
Don't they paint them at the Stadium early in the week and then send them out to get primed or some such other thing after?
That might explain what's in the truck, although you would think the helmets would be airing out somewhere.
I haven't seen a picture of the the truck, it's not USF's equipment one is it? There's always a visiting team's trailer sitting in the stadium for every game.
