Naval Air Station, Whidbey Island, Washington State.

If an Air Force Station is a base with out planes (go figure), than an Naval Air Station is a base with out boats (go figure).....

Anyway, many military installations have all the comforts of home, and than some, including bowling alleys, movie theathers, grocery and department stores, gas stations and the like.

Not sure if this was sold as a pocket piece, a golf ball marker, or what. Reverse is plain. Probably other flavors other than green also avaialble, but have not seen one to date.
