I started and finished at the Lake Mineral Wells State Trailway "gate" at the Weatherford trailhead. Water was turned off at mi 10 & 30. And bathroom was locked at the Mineral Wells trailhead turnaround. Make sure you complete the little loop near the restrooms and train at the trailhead before turning back.
I stubbornly wanted to stay unsupported, so I didn’t stop at any available gas stations or restaurants. I had only 30 oz of water. So it turned into a hike the last couple hours.
