I went to that race last year with the Corvette Forum and parked at their corral. Great WC and ALMS races. SCCA WC is my favorite race series. Cars that you can recognize as the street cars they represent and a good mix of factory and privateer racers.
One of the SCCA T1 drivers I raced against earlier this year (Stan Wilson) drove a Dodge Viper in SCCA WC last year. Was fun to race against a "pro".
