The Larch Mountain Area is posted as a no shooting area by the county now, has been for years. There used to be a public outdoor range in east Vancouver ran by the city parks dept, the English Pit Shooting Range, but it ran out of money, and may not re-open. If you want an indoor range and don't want to travel to Delta Park in Portland to lay down big $ at The Place To Shoot, then Clark Rifles is the only place right now.
I go out the Washougal River road, turn up North Fork Road, and when I am about 5 miles or so past the paved road, I find a place to park that has a backstop of some kind nearby, and that is my shooting range. There are a couple of decent spots up North Fork Road, one has a flat 50 yard distance, and you can shoot out to 100 yards, but you'll be shooting uphill.
PM me if anyone wants more info on the area.
