There's a pretty cool documentary on a group of Live Action Role Players called Darkon up for view on hulu. Very interesting show; it kind of reminds me of Trekkies.
Hulu - Darkon - Watch the full feature film now. (http://www.hulu.com/embed/AM9O_8XhJjp61a1vCt2DjA)
Worth checking out.
Yeah, that is a great show - I saw it on HBO earlier this year. If memory serves, those guys are down in the Baltimore area.
