First car show -- advice??

If your there just for fun and to hang out and help charity just roll with it. Karrin and I go to quite a few local car shows but we never enter a car. We just like to drive them and enjoy them as a hobby. Car shows can be very Clickie and homer in nature. I can't sit still for that long to show a car but we would for a charity. A slant 3 speed manual is a great fish...don't sell her short. She has 3 pedals correct? LOL Enjoy the show! Stock, Original, American collectible would all seem to apply.
