We have a jogging trail here in Dallas called the Katy trail, and it's totally paved and smooth with 2 lanes. It literally runs from behind my house straight to downtown, so it's like a bicycle highway.

One of the most memorable rides I ever had was just mashin down this trail with 3 other very strong riders in a perfect single file line at 2am. We must have been cruising the whole time at about 20mph; there's no lights on the trail after dark, and it's really nerve racking bc someone could easily jump out of a bush and rob you, but it was still just a completely flowing ride to an empty downtown.
