Dave from Dallas here. Recently joined the site, although I'd heard of it some time ago (hey, I even saw the WTF segment on their A Texas Odyssey). I, too, was introduced to FotC through the HBO special, and can't get enough of their series.
If there are any N. Texas fans around, be sure to say Hi. Of course, I'm not trying to discourage greeting from anyone else, but....you know.
P.S. Is there a recognized/agreed-upon term for Conchord fans? Has anyone suggested "Mels"? I mean, from an obsessed fan standpoint.
