They always say that and they are full of it. I personally know of three empty hangars. If you said you are "thinking" about moving they are just trying to dissuade you. A lot of seasonal renters that they are sick of. Also tons of people on the list that have no intention of ever actually renting. They just threw a couple of people out that were using hangars as storage space. If you don't have a registered, insured airplane they won't rent out a hangar. I don't think they take anyone seriously until they rent a tie down first. I'm actually at the airport every day working on my SX-300.
It is quite a drive from Boca, though. 2 hours.
