Haha, sorry, it's only the name that's even remotely secret.
It's a public event held at race city every friday night.
They ran last night, and it was a blast.
$40 to go down there and auto-x. Lots of into on the race city web site. I got over 25 runs in, and I spent an hour standing there watching, since I was running low on spare oil (my car goes through a lot, and the 2 jugs I brought were almost empty).
There are a lot of first-timer's there, it's a pretty quick course, and it's a pretty safe course as well. I wind it up to 120-130kph on the course, and it takes between 60 and 75 seconds depending on your level of skill to run the course.

Next week will be the last one for the year. It's kind of neat, since it's pretty much all after-dark.
For the $40 to auto-x, you get free runs on the drag strip as well. I've taken a pass or two, but I try to stay away, since until 11:00 or so the line-ups are huge.
