I find the smallish airports have a better community..
Sometimes you just have to walk around. I met a number of neat folks at Montauk, Block Island, Northampton, even Lebanon (NH). But as noted above hangars seem to be where the fun is it. There's a great guy at MYF who opens his hangar every Sunday afternoon/evening and people hang out, talk flying, grab some food. It's fun
I left FB 3 years ago and haven't looked back
Need to organize a fly-in to East Hampton Airport before they close it to Hoi Polloi like us
