Like I said before, let's ban charcoal grills in the tailgating lots. That isn't good to breathe in either. Where is the outcry for that? Or let's not allow cars in the tailgating lots as the exhaust can cause cancer too.
Ask your state Rep to introduce such a bill and see what happens. I'll warn you that it can be tough, I've been helping the smoke free Iowa cause for three years now and we finally got this pushed through (mind you there has been consistant support from a vast majority of Iowans to pass this.) I'm guessing that a ban of charcol grills and cars in tailgate lots probably won't poll as well, but we won't know until there is one.
