David,
You will have a great time. The cars are all outside in tents and you can talk to some of the car owners about the cars. There are a lot of cars there, and there are some really nice vendors inside selling collectibles.
The only thing is like I said, you cannot sit in the bidders area, and we got a little tired of walking around and watching from the rear and the sides, but overall, it's worth going there for sure. They have single day tickets and weekend passes too.
Enjoy!
Brian
