Doesn't matter if nitrous is illegal.. There were several cars out there that actually came off of a trailer, and are absolutely not street legal--i.e. track/drag cars. That's what cruise night is all about, and that's why you can run neons and strobe lights and all of that junk. Hell, I even saw a Chevelle do a smokey burn-out next to a group of cops in the middle of the road and they gave the guy thumbs up. I don't think they care much about things like that on cruise night.
