Moses Lake Municipal, Moses Lake, WA (W20)
Correctly identified first by Elliott Drucker
Little Moses Lake Municipal - also known to some locals as "the in-town-airport" - is tucked up close by the massive and better known Grant County International Airport, which dominates the area (and attracts quite a bit of heavy iron, so if you're trying to slip in to Moses Lake Municipal, keep a sharp eye out!). It's a quiet, low-key airport on the southeast edge of town.
