I used to go to this, since it is right up the road, its $10 for the first 100 cars. Rest of the cars have season passes that sell out in the spring. Not a great venue, it is in an industrial park and cars park around the loop road, approx 1 mile around. Then the rest park in interior parking lots. So its a bunch of walking to see all the cars hiding in nooks and crannys. I have not gone in a coupe of years since they started the money collecting
