I've seen news pieces on people living at airparks. I've been by Cameron Park, California in Eldorado County where they have an airpark. However, I was looking up the name of a pilot who I saw named before and found this about the house he bought at Pine Mountain Lake Airport near Groveland, California. He's a test pilot for United mostly based out of San Francisco, so he flies there and says it costs a little bit more in fuel costs to fly his plane than a car. However, he flies to San Carlos Airport and not SFO, where I believe landing and storage fees would be crazy expensive for general aviation. He says he keeps a car at San Carlos Airport.
