Is there a road race track in North Texas anywhere? I live in DFW. If there is, what are the requirements to be able to take laps on the track? Any info would be appreciated.

The closest track to Dallas is this one (http://69.53.67.194/~motorsportranch_com/). As far as information about doing a track day, check out:
