Geeks and guns are a natural match. Open-source software is about getting freedom; personal firearms are about keeping it. Besides that, hackers gotta love anything where you get to tinker with complex hardware that makes loud exploding noises.
If you're interested in attending or organizing future Geeks With Guns events, Jay Maynard has started two mailing lists; gwg@conmicro.cx for general discussion and gwg-announce@conmicro.cx, a moderated announcements. Subscribe by sending a message with a body containing the word `subscribe', followed by a space, followed by your email address. For convenience, here are mail-to links to the request addresses for gwg@conmicro.cx and gwg-announce@conmicro.cx
It's a tradition now. I expect to be organizing these as long as people keep inviting me back to hacker conferences.
See my Gun Nut page, which explodes quite a few myths about guns and gun owners.
