Yea. Unless it's a Tuning Day, or incredibly bad weather, you'll have huge turnouts.
For OVR SCCA, it wasn't unexpected to see 100+ cars each event. Even with that, they got AT LEAST 5 runs..
With NORA, their numbers aren't as much, but with the 60+ second runs, even if you get 5 or so runs it's certainly more time in the seat versus OVR.
OVR is fantastic though, you can't beat running with them. I'll be in Columbus plenty of times
