I took my '69 Road Runner to a CC Street Machine Nats at Indy one year (in the early '80s). Worst car experience of my life. The participants blocked off streets and formed a cattle chute and made each car do a burnout in water and bleach. They stood right next to the cars and threw beer on them if you didn't please them. The cops were out of control too and acted like thugs. They banged on fenders with their billy clubs to control traffic. I walked from my motel to witness one of the larger burnout fiascos and the cops showed up each with a K9 and proceeded to "clear the street". I got clubbed in the back of the head while trying to cross the parking lot back to my motel. I turned to look at him and the veins were popping out of his neck. He was holding his German Sheppard with one hand and had his club raised in the other. He said, "just try something, PLEASE just try something". I kept my hands in my pockets to avoid possible provocation and they made me run the rest of the way back. Left the next morning for home. I figured it might not get any "better" than that and I didn't want to stay around to see if it got worse. Never attended another one.
I would have rather had to change a cam in the parking lot. That would have been a LOT more fun.
As for the voting, thanks guys

Natural is the winner by a 2-1 margin. That's pretty much the way I wanted to go, so I feel better now.
