Conspiracy theories come with the territory here. And at Barbec's Restaurant on the other side of this sprawling city, six men sit on a covered porch and convene a meeting of the North Texans for 9/11 Truth group and talk about the government's lies about 9/11.
The group has 50 active members; 200 on the mailing list. And they number among many thousands who, after years of investigations, don't believe the official version of how the World Trade Center collapsed, who was responsible or what the government knew and when.
Politics doesn't have anything to do with it; two were once staunch, Bush-voting conservatives; two are progressives and two weren't even interested in current events until after the 2001 attacks.
"Before 9/11, I was a working class person, going through life, pretty much accepting everything given and told to me," said Bryan Black, a 50-year-old carpenter from Commerce, Texas, "I'm starting to see things. I'm more open to skeptical conversation."
