Currently... a desk... at an Air Force base... with the GA ramp right next door.
In the past, I've flown single engine planes and helicopters. It got expensive considering my wife wasn't into flying. She flew with me once when I got my PP-ASEL, once more when I got my Helicopter rating, and once more when I got my Instrument rating. It's kind of an expensive and time consuming way to get her to go flying. I keep threatening to get my Commercial and CFI and semi-retire as a helicopter instructor. She doesn't like that idea, but I tell her there aren't any semi-retirement nudist jobs out there!
Small aircraft, and I'm big. I can only manage about a 150-lb passenger and stay under gross, and I don't know any small nudists. Then, I also fly out of a public airport - not much chance to get nude before flying, and the control sticks make it hard to undress in the cockpit. So it goes.
