So I went to this on Saturday so I have a bit more to report.
First of all, it's very laid back a casual. There are all kinds of cars and bikes, everything you can imagine. Slow & fast, high quality & pieces of junk, race cars & stock cars; you name it, it was there. I certainly would not feel out of place or uncomfortable running my Z there.
Second, they have max of 175 registrations each weekend, and that $200 covers you for as many times as you can race. It's not just one pull, it's how fast the line goes and how many times you want to get back in line. I was only there Saturday for about 3 hours and I saw several cars make 3 runs in that time; others only 1 or 2.
What I would strongly recommend is doing what I did (which is what my nephew suggested). Pay the $10 per person just to watch for a day. Drive using a vehicle that you can take a bicycle along so you can park then just ride around to see the sights. Pack yourself a cooler with drinks and sandwiches etc for food. Bring some binoculars, and if you have it, a radio to pick up the announcer (not sure what kind, it was my nephews but that could be looked into). That way you can hear the speeds the vehicles end up making.
We only stayed about 3 hours (my nephew and his day were there all day) and it was certainly a fun way to spend a Saturday. I wouldn't say it's a total blast, but it was fun and interesting and entertaining for sure. Go to meet lots of nice people who are into their cars and bikes and it was just a casual fun day. It's a real cast of characters for sure.
And THEN, if you feel you like the idea, sign up and race the next time. I know I'm considering it now. Need to check the rule book more thoroughly first, but I'm certainly more interested than I was.
Cheers ---- Bonzo
