Hi! I'm new to cycling and in the DFW area too. Now that the rain has stopped get out and explore the bike paths - I've been surprised at how extensive they are. Of course, convincing cars that indeed the road is clearly marked for bike traffic is another story,
http://cycledallas.org/ has lots of info and is a good place to start. and
http://bikedfw.org has tons of info and a listing of local clubs in and around the metroplex. Welcome to town! -Shelley
