I don't know if this information is of any value to anyone on IOW, but I just got off the phone with the fairground office at PAS. I was able to confirm with them that the previous camping area (both grass and paved) will be inaccessible at the Oval Nationals, and RVers will be redirected to the north end of the regular parking lot.

The nightly dry camping fee of $25.00 will still apply, even though no hookups will be available. The woman I spoke to stated that the regular campground was always considered dry camping, and that anyone who previously was hooking up to electric and/or water, was doing it without the permission of the fairground, as there was no agreement between the fairground and track to provide these services.

Just a guess, but I would imagine that rest rooms will also not be available when the track gates are closed.
