Port of Ilwaco, Ilwaco, WA (7W1)
Correctly identified first by Elliott Drucker
A quiet little strip sitting on the southern end of the Long Beach Peninsula where it meets the southeast Washington mainland, just north of the wide mouth of the Columbia River. I've landed there on the skinny runway several times and every time there has been some interesting gusty winds on short final. so stay on your toes! There's not much at the airport, but it's the closest public airport to the beautiful beaches of the peninsula.
