No fun fields for me. Maybe 4Cruizn can tell you about that side. I stay on the other side since the swap area is there.
The group we are with get there on Wed night, Thurs Morning to setup a tent for us to park around. We always park on the right side looking down the track. If you come out, you'll park with us if you like. We park between the Pit parking lot grass show car area which also is at the top of the swap meet area. Show cars have to be there the first day for judging, like pink panther said so after that day, we park wherever we want.
My son and I can share a bed, you can have the other one, if you bring a friend we can also get a rollaway bed in there for a few dollars more. 2 years ago we had 3 in the room, each paying for a single day.
Things can happen in your life where you might not be able to go next year. Things come up.
