Well, I recognize Roger & Mrs, Raydar & Mrs, Scottb & Mrs, TopNotch & his brothers, Fierofool, CowsPatoot, but I'd have to guess for the rest. No idea, really.
Looks like a lot of fun, except perhaps for the guy with the Thunder shirt (I think he drives a silver notchie).
Roger was a sheriff?
TopNotch, is that a bee on your hood? I'll take a wild guess that its name is Buzz.
