I wandered around for a little while this morning. It was kind of chilly at times and a bit drizzly as well. The Cup car looked like it was running pretty well, although it didn't seem to have the power to compete with a lot of the AI Mustangs. You need to get a less restrictive exhaust on it, so you can hear it over the other cars.
Were you guys helping with the GoCar(??) Mustang as well?
In an unrelated note, I watched with half-covered eyes as a guy from PA helped pull out a stuck spectator by his radiator core support. They got it out without removing any critical components, luckily, but I wasn't too sure for a while.
