So I regret to inform you guys that my efforts are in vain. the county said that the request needs to be input 180 days in advance. That being said I just checked the site availability and there is still plenty of campsite open with the entire OHV area still open. I will be booking Cabin #1 for myself and The chapter HQ will be at Cabin #10
The cabins (including the event's HQ cabin) are in Campground "O", which is also where any green-sticker/OHV vehicles have to be, and where most of the RV sites are.
