I mostly ride on roads, only did the Lake Mineral Wells trail one time, that was on my Worksman cruiser.
The Katy Trail tends to be crowded with joggers/walkers, or was last time I was there, that's why I didn't mention it.
On the route around White Rock Lake, I normally use the roads about 3/4 of the way around, and use the trails otherwise. The sections of trail that people don't normally ride on are bumpier and narrower. I'm usually out there on weeknights or Sunday afternoons, and crowds aren't usually too much of a problem.
