Like Pat said this was an "Ohio Valley Region SCCA" autocross, they have about a dozen autocrosses a year. For the track events "NASA" holds what they call "High Performance Driving Events(HPDE)" and they are you with your street car and an instructor on places like Mid-Ohio learning to handle your car at it's limit.
The autocrosses take place around here at Cooper Stadium, OSU lot(315&Ackerman), and National Trails. The HPDE's happen at Mid-Ohio, Nelson Ledges, Putnam Park, and pretty much every major track around.
