HWD, I can relate to that road northeast from San Jose de Comondu. I took it back around 1990 in a Baja bug. Back then the road was well defined, but the locals had stopped using it a few years back judging from it's condition.
The road was on the AAA map back then.....and shouldn't have been. They don't upgrade those maps very often. Like never!
I was in my Baja Bug with a companion. If I'd known what I was getting into, I'd have never gone that way. As you did, I felt very vulnerable out there.
Congrats on the successful transition of that route. You guys rock.
