I started to post this in another thread, but didn't want to hijack or derail it. All we keep hearing about is the decline of GA, less pilots, less airplanes, etc., etc. Then everywhere I go, I hear about hangar space being at a premium if even available. Airports all around have waiting lists years long. Now I know the common problem is non flying airplanes tying up hangar space, even though not true here, but what is causing the supply/demand issue for hangars in a declining industry? Are more people preferring to hangar rather than tie down outside? I'd love to hear other people's theories. Given I am an airport manager, it could be useful.
