Didn't see much derelict stuff at Naples earlier this year, but maybe I was looking in the wrong place. Nice airfield, though, and nice people...
I don't think there are any boneyards close to Florida. If you really want to see that sort of thing, I'd fly commercial to somewhere "out West" and rent from there.
You may be in Florida on business, but do you have to stay there once business is done? I used to escape Detroit at the first opportunity...
