If you have absolutely nothing better to do, it's not bad. I went last night, they open at 6, I got there at 6:45 and was car number 106 if you get the picture. I turned in my tech card and got right in line, I did three passes in the whole night. Probably could have done 4 or 5 but I took a break to let the car cool and grab some food. I've been nights when it's a ghost town though, so it's a crap shoot, usually pretty crowded though.
