Hey Oceanus, We hired an outfitter to drop us off with our truck. They then were to come out 3 days later and drop the truck at the other trail head. We had an extra set of keys and would pick the truck up. Unfortunately one of us cratered and we returned to the same trailhead the next day.
At that point we hitch hiked back since we were early. I believe the cost was $50? The outfitters are easy to find in Terlingua.
A brave man to solo this hike. I would do it but hesitate a little due to the remote location... I know I will one day but have to get back in the swing of things before I do (plus tell the wife I'm going elsewhere
),,,, Good luck and let me know if I can do anything!!
