Okanogan Legion, WA (S35)
Correctly identified first by Ghery Pettit

A very nice small town airport in the Okanogan Valley in north-central Washington. When I stopped in there I was very pleasantly surprised to find a lot of amenities. Free courtesy car, pilot lounge with snooze couches, vending machines, bathroom and showers. Not too shabby at all for a small town airport. I'll be back.
