nah, not everywhere... but most states.
As for cooling... while I do think it "helps." I don't think it's all that much. You effectively have two radiators... one behind the top grill, and one lower and behind the first radiator. And MAN OH MAN, that bottom one can get covered up EASILY with debris.
I've been debating finding a way to cover the bottom with a grill or something, so debris won't go in there. A few months ago, I yanked out quite a bit of dead leaves.
