kenrayc beat me to it.
The Columbia River's mouth is nowhere near Clark County, actually bordering Pacific County to the south, which is all located about 80 miles west of here.
[size=8pt]Original post and footnotes:
Near rural Clark County is the unincorporated census-designated community of Hockinson, wherein years ago me and my friends used to record background music.
And that's one of my favourite destinations. The place is a dump, lots of the old buildings are getting pretty run down (especially as you move farther away from the main drag) and as a result, it has a certain beauty that seems to be getting increasingly harder to come across these days down in Vancouver. 'Tis where I go when it's a nice Summer day and I need to get out of the city for a few hours.
There's almost no traffic there, either, and seemingly little traffic noise. You can actually hear yourself think up there. It's kind of surreal, and a shock when I finally *do* make it back to the 'Coove and the droning, inescapable sound of internal combustion engines all aroud me. I have to turn my CD player *down* when I'm there, well, I usually end up turning it back *up* coming back!
Look up the lyrics to Three Dog Night's cut "Out In the Country" for more information.
