I would be happy to organize a hang in North Alabama. Would love to see what interest we would have and welcome any ideas. I've got a few myself.
(Yes, you Tennessee folks would be welcomes as well :P)
I do know of a great greenway near Guntersville Dam that is public use, and has tons of trees. Ah, just lemme see interest and ideas and we'll go from there. But I love the idea of a hang out.
