NASCAR New Hampshire Private Camping?

Taking a stab in the dark that someone here may be able to help me out. Heading to the NASCAR race weekend at NHMS on Sept 25. We have always camped on the speedway property but have heard some goods things about a private property owner across the street from the main entrance to the speedway who does a real nice setup for campers. From what I have heard, rates are about $200 for the weekend. Their property extends all the way up the hill and has quite a bit of space. Here's the rub...because they are not a "real campground", no one seems to have any contact information for them. I've tried Googling by every keyword or phrase I can possibly think of and still have come up empty. Anybody here on the forum able to shed some light on these mysterious hosts? I'd like to give them a holler this year.
