Show up at most any Autocross in the area and you will find many people happy to take a passenger along for a ride. Check the events sticky above and you can find a list of the events. The ones at Brooksville will require that you register at least a week in advance, even as a spectator. Better yet, bring your car and give it a shot! There are free instructors at every event who will ride along and help you learn the ropes.Scott
