Us 3 Aussies travelled that road from Dulce thru to Pagosa Junction last September, the road was a little rough in places thru the reservation area, but in general it was fantastic and beautiful part of our trip (I asked advice about this trip on this forum) and it was well worth it. We didn't know about the Arboles tank though, which is now a shame, something for the next trip.
I love that sound track on the first video Roger, I asked about that once before I reckon, was it a band out of Durango??
