I have visited there a couple of years ago for one of Mark C's winter series races. It appears to be a good facility except for the seriously dis organized parking and the utter disregard (at least that day) for handicap spot use. I don't drink the social media kool-aid so it is great that you are attempting to broaden your horizons by posting here. I am not an off-road guy but I will be happy to steer any seeking that form of racing from our area toward you if you would do the same for on-roaders in your area to visit Kannapolis Raceway Park.
Good luck for the coming season.
