It's best to check the racetrack rules....which I just did for you.
๐http://www.doverspeedway.com/parking-info/Seems the rules have Quiet Time from 11:00 to 6:00.
๐There are reports of people there that break the rules and run their gennys all night..
There was a nice rig beside us at Talledega that ran theirs all the time....but it was so quiet we could not even hear it so it did not bother us or anyone else.
There seems to be quite a bit of off-track camping that you should check out.
