Ocean Shores Municipal Airport, Ocean Shores, WA (W04)
Correctly identified by Karl Gruber.

Located on the western shore of the Grays Harbor estuary, Ocean Shores Municipal is a great field that sees relatively little activity (probably because Hoquiam's nearby Bowerman Field has both fuel and a popular cafe on the field). There's not much there at Ocean Shores, but there's a relatively new pilots lounge, and on-and-off plans for a FBO and other improvements. This is actually the second Ocean Shores airport. The original town airport (Corning Field, also known occasionally as Avco Airport) was engulfed by the town's growth (and a golf course). In 1986 the new airport was built as a replacement.
