I went last night (Friday), got there at 5pm and there seemed to be only a few cars that showed up. It may have been the weather, started raining around 7pm. I got 6 or 7 runs in. The people there were friendly, and everything seemed to run smoothly.

FWIW, my best run in the rental car (2010 Ford Taurus Limited) was 15.678@92.13 mph, 2.345 60', 0.055 RT. That was with traction control off, shifting from 1st to 2nd at 5,000 rpm (the 1-2 shift is really slow) shifted 2-3 and 3-4 at 6,000 rpm, but really finished the 1/4 right at the top of 3rd gear.
