My Home Field

Earned all my ratings here...from PVT up through CFI-IA. Great facilities, 2 flight schools on the field, maintenance is top-notch, Garmin dealer, and plenty of hangar space (not cheap, but not overly out of line for the area). AIrport has been in operation since the 1920s, and has a good working relationship with the town after many years of issues during the 1980s...could stand as an example of how to go along to get along in the most densely populated state in the US.
