I'd be interested in a centrally located Dallas craft group, but definitely not a "DFW metroplex" or "Dallas/Denton" group. All these cities (Arlington, Fort Worth, Denton, Dallas, etc) get lumped together, but they're really too far away from each other for it to be practical to expect people to drive an hour to get there.
Really, I must agree. I think an Arlington/Fort Worth one would be sufficient. And then Dallas can have a separate craft group.
