Yep....I'm in Houston a few times a year on business......not much there...but it is getting better. The hill country around Austin has some great riding. Most of the Dallas trails are semi flat...but we do have some elevation that we've made good use of. The 6hr video is from a "mountain" (I use the term likely)ridge that runs through Dallas. The trail is on the highest point in Dallas county. We have 1650 ft of climbing in the 8.8 miles.
Hope to get back to Fl later in the summer.
