Yeah, its silly, but its also winter and things like this are posted at this time of year, and this is America where we do things because we can. At the local bike night joint, they installed a "burn-out" trap. Its a device that clamps onto your front tire while the rear tire sits on a concrete pad, straps are attatched to your bike to keep it upright and tied down. Guys would ride up, hook up, and burn out, filling the whole parking lot with dense white smoke and very loud exhaust noise, a few would run the tires till they blew, a few were suprised at that, not sure if they knew that doing this would blow your tire up. When my tires are going to be replaced, we always do a burn out and take a pic, we got a few good ones going back to the early 80's.
