And, as suggested by the locals, this road was somewhat washed out due to the recent rains and was clearly not travelled on any regular basis. As we made our way north the road continued to deteriorate and the riding kept getting better and better.
Then we reached the first obstacle - the road was completely washed out.
A car or truck would have turned back at this point but we were able to get through on motos without too much difficulty by skirting the edge of the washed out area. As long as neither of us fell into the pit of despair things would be okay.
Beyond the washed out area, we enjoyed more great riding.
We came upon another area where the road disappeared at a fence and a arroyo. With some exploring JT found the way across the arroyo and back onto the road. As we neared the western end of the road, where it intersected with the main dirt road between Galeana and Rayones, the road started to improve - clearly this part of the road was being used on a somewhat regular basis.
Unfortunately, we encountered a locked gate. Now what should we do?
This is cattle country so fences and gates are common. It's how the locals keep their cattle from wandering off. However, just like in Texas, the roads are public, built and maintained by the government. So it's no big deal to go through a gate. Just make sure you leave it the way you found it (i.e. close it behind you if it was closed when you got there). A locked gate is another story - it means that either you are on a private road (doubtful in this case) or one of the landowners is pissed off at his neighbors and this is his way of limiting their access.
In any case, an examination of the gate revealed that there was just enough slack in the chain that we could lay the gate down and ride over it. So that's what we did.
Once past the gate we put it back the way we found it so the cattle wouldn't get out and continued on our way.
So, the road was there and it was really fun but I can't recommend it to you until the issue with the locked gate is resolved. However, JT has pointed out that there is another road that bypasses the locked gate that might be an option. We didn't explore that other road this time as it was late in the day and the afternoon rain clouds were gathering. Somebody needs to check it out (hint, hint, MexTrek 2016, hint, hint).
