Trying to figure out pics I hadn't posted.
1. I think this had an outboard motor, on it's side, chain driven to the rear wheel....anybody know?
2. I don't know this coupe. My bike running unstreamlined barely visible in back....only pic of it that way, that year (and only half shows).
3. On the motorcycle line (left side of the course). Always good to let your pit crew warm it up for you....you can blame whatever goes wrong on whatever they did!
4. Who's kids are these and what are they doing now? We sure were informal about pitbikes, in those days. Notice the tire collection in the back of the El Camino....one road warrior, one Class C Universal, and an iffy front rib. Probably all tube type, to boot.
