We went to the "Commercial Point Grand Prix of Karting" today. It was in Commercial Point,Ohio. The Carts had Kawaski 100 motors in them.They could get up to 75 mph.

From Their site: Lined with fence, straw, and barrels the 6 turn 1/2 mile course winds through the historic streets of Commercial Point, Ohio. The famous 900 foot straight away provides spectators the chance to see up-close photo finishes and gives karters the chance to push their machines to the limit at speeds reaching 75 MPH. http://www.cpgrandprix.com/
