Driving a long distance in hot weather without AC?!

I drove the Fusion and enjoyed the ride. My girlfriend and I made the promise to drive the Scamp out next year. Some good suggestions here.
Remember, a '75 does not have vent windows. I enjoy using those in my Road Runner, but no dice in the Scamp.

OK - you can resume busting my balls.....

Plan ahead for next year because Carlisle is over now. By then you could put AC in your car and not need any (LMAO) Vagasil.
