I think I saw one of the FBO website advertising $400 or something like that for a full service heated hangar. There are some reasonable t hangars too, I would guess there is some years of waiting. I personally would prefer t hangar... but might have to take what I get. I will explore the airport you suggested. PDK hangar situation is even pathetic from what I can tell and I definitely want to avoid the drive from west side to PDK if I can. Ideally I need to be close to KATL and a GA airport . That might be asking for too much
Is heat really necessary there? The low tonight in Atlanta is 8 degrees warmer than we normally set the thermostat in our hangar.
