Oh boy, I was a tech insp for a race organization & the director told me, go tell the guys to put heat in their motors. I asked, Where's the ambulance? he told me, Don't worry about it go get ready - NO, if it's no big deal why do we require helmets & belts to put heat in? While we argued the ambulance came in, THERE YA HAPPY NOW? - No, I need a hug. YOU A'o get out there
