Mopar Nats Registration?

Yeah, we toured around the whole facility looking for a parking spot. Went to top end lot first, but didn't want to have to squeeze my car in there, so we went around front, got caught in major traffic jam, and found out that every lot was closed and cops were stationed there to keep everybody out. One cop said to go to the top end lot as it was only one open. Well, a half hour ago there were maybe 5 spots there, and we passed about a hundred cars when we left there. I was thinking, **** we may not get in, but my buddy said tell the cop we are entered in the show. Went back to the main lot entrance, told cop we were in show ( was driving my '06 Magnum SRT8) and he waved me by !!!! We found the LAST open parking spot and walked right in.
