Case in point, Pend Oreille ORV by Ione. Been riding here for last 3-4 years. Trees are often taken care of by those other 2 wheeled riders. Snow melts off sooner than here. There are some big trail loops. Terrain is some of my favorite as it is quick to get up to high elevations. You will find lots of rocks, several creek crossings, many small lakes and few other people on the trails themselves (most seem to all stay lower). Get a map. Not the ORV map. A real map (ie the Colville FS map).
Pretty, huh? One of these rides with capped off with some elk steaks on the bbq and a few hop sodas. Damn, doesn't get much better. Ride ur bike.
