On March 9 and 10, 2019, Amy and I drove El Taco (our 4x4 Toyota Tacoma) on a reconnaissance of the NM BDR Section 6 from Grants to Cuba. See Google Map
https://drive.google.com/open?id=16QnSeWIaky3CgQ6DTsAPwtZ7RebJOqTF&usp=sharing Starting from Grants, we headed up hwy 547 onto the shoulder of Mt Taylor. The paved road turned into a good, graded gravel road but then got covered with snow. Eventually, the Taco got stopped by the snow and we turned around and headed back to Grants. We took hwy 605 from Milan to San Mateo and reconnected with the BDR about 2.5 miles north of San Mateo. About 4 miles north of where the BDR hits the pavement on hwy 75 (unmarked), things got very confusing. If you see these signs
turn around, head 0.4 miles back and turn north on a dirt road. There are a couple to choose from, all unmarked, and we made several wrong turns before we got on the right road. Best to have a GPS with the BDR track on it and use it in this area.

Once we got on the right road, we had clear sailing all the way to Waypoint 2. The road was hard packed, dry and clayey, with very little sand. Overall a very easy road. We encountered several gates along the way, but they were not locked and we passed through, leaving them as we found them. At Waypoint 2 we took a short detour to ride up onto the mesa to the south on road 239 (unmarked). This fun road is more challenging then the BDR but takes you up into the pine trees on the mesa with spectacular views to the north. Back at Waypoint 2, we continued on the BDR to Waypoint 4 just to the north of El Cabezon. The road was very good in this stretch. From Waypoint 4 we headed north to a beautiful camp up on top of a mesa. The views of El Cabezon to the south and the mesas to the north were fantastic.
The road from Waypoint 4 to Highway 550 was not quite as good as what we experienced prior to Waypoint 4 but still not bad. There were some patches of sand but otherwise no major obstacles.
Overall, we thought the route would be quite doable on dual sport bikes, even though we did it in a 4x4 and we are quite inexperienced dirt bike riders. We look forward to repeating the trip on bikes in a few weeks when the snow on Mt Taylor melts.
