Incidentally the FAA data lists the correct coordinates for this airport:
https://nfdc.faa.gov/nfdcApps/services/ajv5/airportDisplay.jsp?airportId=WN96
47-24-16.46 N / 122-29-17.65 W
which Google Maps shows is the actual location of Misty Isle Farms:
https://www.google.com/maps/place/47%C2%B024'16.5%22N+122%C2%B029'17.7%22W/@47.4076921,-122.4952716,13.75z/
So, not sure where airport-data.com got the incorrect data from.
