Usually about 5 or 10 of us - just a bunch of ex-Army buddies who like to fly R/C, very informal. We also shoot, go camping, fourwheeling and game together.
We don't have an AMA sanctioned "Club" but we still have fun. Nothing against formal clubs, mind you, just not my cup of tea.

Never did a BBQ while flying...not a bad idea at all. Have to suggest it.
