Grant county fairgrounds is for hire,,with all the shit we need,,basic rental is $350,,showers, a kitchen, a big bilding to hide in if it rains, tons of tent sites and RV spaces on site!
I camp there free on my way through town sometimes, the space along the river beside the horse arena is always open year round. They have no facility for you to pay for camping overnite, but there has never been a problem with showing up and pitching a tent.
So I send them some dollars each year to apply to their general fairgrounds fund.
A group effort would most likely be welcomed, they are very receptive to the annual BMW Riders of Oregon Rally (Chief Joseph Rally) each year,the town makes money, the folks are friendly and receptive, and it is right in the center of some of the best riding in the state, gravel or asphalt.
it's a thought,,
