Why would that be a problem? Just need some framing and canvas or light sheet metal. This might be a good car to have right behind the engine...(If metal covered)
I know I have ridden out there and either been burned to a crisp or soaked to the bone....although there was that one year with the snow....
I think though the whole idea is to be 'out' to get the entire picture. Are there enough gons to have a covered one say near the snack car with two benches back to back in the center and one open one?
I guess it goes back to placement again doesn't it?
