They allow tuning & such, if you put on something that looks like a race, they might shut us down. Better check on that. For a race, they'll want to have fire, medics & stuff on hand & that runs into bucks. Without it they have liabilities.
We might be allowed timed runs & compare times with each other. We might even be able to have the cars spaced 20 or 30 seconds apart to maximize the track usage and everybody get at least 5 laps in each day - depending on how many show.
