OK guys take it easy on me.

I have owned 4 Camaros now in my lifetime, but have only been to a couple of car shows as a casual observer. Help! Now I have been invited to take place in 2 of them over this weekend with my RJT. I don't want to look like a complete idiot. What do you do? I know get the car clean and shiney, but what else? I assume you stay with the car while on display? Any tips would be greatly appreciated and thanks so much.
