On sim I was searching around for short runways and fun unusual places to fly, and stumbled upon this airport located just on the Oregon side of the Columbia river (which separates Oregon/Washington) as it flows thru top of Oregon a little inland from Portland.

I must have simmed takeoff, landing and patterns around this airport over a hundred times, and keep coming back to it.

Looks SO MUCH BETTER in X-Plane by the way.

Anyway, it's on the list. And besides a fun-looking runway in a fascinating rural location, I simply must visit the waterfalls there. I find waterfalls awesome in general, and by all the photos I found of this one, it looks spectacular.
