BB75....there is a thread here that will explain the need for aluminum foil protection....click on the website in my topic about foil and see what I mean...Every time Vedder or Eddie or 4Salt or GoHarley or SlhdH2o get going on their liberal high horses I wrap foil around my head to ward off their damaging vibes....the rays they omit can go right to the brain like a meal worm if you don't protect yourself.
