I watched the Supermoto in Columbus in 2003 and the asphalt race at Charlotte. Charlotte was a relatively short track. A few crashes at low speed at Columbus, one being Chris Fillmore, and no crashes at Charlotte. A half mile is probably too big, the short tracks are likely very much like a bit bigger indoor races on concrete. If all racing was based on injury and fatalities no races would be held. Pretty simple. If that's what guides your attendance did you quit going to dirt track races? By the way, I actually think more of the crap comes from you.
