You looked at the acreage, did you you look at the vender and showfield spacing?
I don't know know where they are doing the Hellcat amusement rides, but my guess is the lot they have used for the Hotchkis sponsored 'autocross'. That's off the map to the north. There used to be off-site 1/8 mile drag racing. I assume that's no longer. So that gives you an idea of how dense, how many swap sellers, how many show field cars there are if you look at the spaces.
The special or theme related cars go in or near one of the shed buildings. Building 'Y' had the '70 Trans-am theme related cars the year I went.
