In the old days, (pre- 9/11) you would hang out at the airport, with your crush hat and epaulets, in a vain attempt to avoid going home to your family, and your adult responsibilities. The "shack" as we old timers called, really was a shack, and it was a bastion of swaggering, eagle eyed, 1,000 yard stare, masculinity. This is where you told dirty jokes, and lied about your sexual prowess. It's where you heard stories of aviation daring-do which you would then borrow and weave into your own stories, so your stories would be less girlie and more exciting.
Now they have FBO's and they allow women, so all of that is a mere memory, an almost forgotten part of aviation history. No more dirty jokes, no more stories of sexual prowess, and every time you try to tell a story about your adventures, some emasculating woman will say "BUKKSHOT! Don't you have to go home and hang some curtains?"
Now, you have to find "The Secret Hanger". The key to finding it is the overflowing trash barrel, filled with beer cans and beef jerky wrappers (I personally like the teriyaki flavor). Next, to make sure it's not a trap, check to see if it has girlie calendars and pinups on the walls, and at least one macho motorcycle or sports car inside (they don't have to be in running condition). If it's too clean, or the plane is too new, or doesn't have a propeller, or has a Cirrus parked in it, keep walking. That's not the hanger you are looking for.
If you think you are in the right spot, open the door, and announce yourself by holding a six pack in front of you and saying "I brought beer." This is the best way to elicit an invitation to come in. Other than the words, "Help yourself" and "I own the Cessna 172M three hangers over." Don't speak unless spoken to. Listen intently for about 3 months. Eventually someone will ask your opinion on something. Don't screw this up. You will never get another opportunity to speak again if you do.
This is the safest way to meet other pilots.
