I just learned there is a outdoor kart racing track in Riverside

Driving a kart is a hell of a lot of fun, but it's not cheap. $25 bucks a 10 minute run from what I read http://www.adamsmotorsportspark.com/

NICE kids motor cart from the early 1970's, made by the McDonough Power Equipment company in McDonough Georgia, model T10

manufactured by McDonough Power Equipment Inc., located in McDonough, GA. in 1970's. It is powered by a Briggs & Stratton engine and a metal body with fiberglass fenders, inflatable tires with wood spokes

you can see a variation of this at http://www.1stdibs.com/furniture_item_detail.php?id=286831
