@tk @feld Apropos that... You may know that little prop airplanes are pretty loud, which is why everyone who flies them wears active noise-canceling headsets. And so, my tailwheel instructor lived in an airpark, and I commuted to his house for lessons. One day, I talked to his wife about living in an airpark, and she said: "It's amazingly quiet. We had no idea how noisy it was in the city until we moved here." I said: "But you literally live next to a runway where airplanes take off." And she said: "Yes, but that's only once in a while. The city noise is constant."
