Hover is still open plus there are some gravel roads above it. As mentioned above, there are some dirt roads on the edges of Badger Canyon. Saddle Mountain is OK up near Mattawa, although I trailer up there not ride. The Mtn. bike trails near the state police office are OK but motors are not popular there. There are some roads and trails near Clodfelter/10th intersection. Also some out towards Jumpoff Joe.
A little farther out, there's the windmills above Wallula and a few roads. Out toward Prescott along the Snake.
Lots of pavement and gravel mixed in to all these.
