I know people that live in and near downtown Fort Worth and work in Dallas. Fort Worth doesn't have much of a rail system, but there is a commuter link to Dallas. Fort Worth itself has a lot of easy rides to large portions of the city if you live near downtown, and the neighborhoods are "permeable" in that you can go long distances without having to ride on the busy arterials- just cut through the neighborhoods. Also, the Trinity River has trails that lead out in various directions which are used by commuters. Here's a sampling of riding in and around dowtown Fort Worth. There is also a very welcoming bike community here in Ft Worth- easy to make friends.

Not sure what kind of work you do, but the local economy is doing okay.
