The upper deck here in Austin are three lanes. There were no car's except for the racer's. Also, we always take safety serious. I know racing dangerous...but the people I know are always safety concious. I know people in general forget about those measure but I know these guy's and I can vouch for them. We had to put that Supra owner in his place anyway. His plate did say 200MPH on it. Either way it was a good run. Richard
