Airports
I learned to fly at Wiley Post Airport in OKC. Good training facility. Good runways, controlled field with friendly controllers, a variety of VOR and ILS approaches. Decent restaurant. Friendly and professional FSDO on the field. For that matter, Oklahoma City is a great training environment all around. Several airports, a great variety of approaches, friendly TRACON, real crosswinds, and real weather.
I liked Prescott, although it is overrun by Riddle. Nancy's is a good restaurant. With the exception of one controller, who eventually married one of my former students, the controllers aren't that friendly. I suspect they are burned out by the daily load of Riddle aircraft.
I will include McGehee's Catfish Restaurant in southern Oklahoma. It has a grass field that slopes, and is a bit of a challenge. Not my favorite airport per se, but the farm-raised catfish and hush puppies are out of this world.
I took a flight into LaGuardia once. I didn't like it at all. The terminal seemed cramped and dirty and the runways seemed crowded.
Montreal Dorval is an alright big airport. I liked seeing the unfamiliar commuter airline aircraft, e.g. Air Alma, etc.
DEN is one of the best things to happen to Denver in a long time. Beautiful facility. Spacious. Quite an upgrade from Stapleton, which was a classic prop airport during the fifties (with a GREAT restaurant, with a fantastic view of the ramp and those beautiful DC-7s, etc.), but suffered from all the Rube Goldberg "improvements" after the fifties.
