As we would find out, there is a lot of "high desert" in northern Mexico. We were on a lot of roads that have sections where you can see the road disappearing straight over the horizon 10 miles away, alternating with sections where the road has to go over a ridge or minor mountain range.
First snack and photo stop in Mexico:
We got the vehicle permits at the border station, but no-one there checked them. I hadn't realized it, but there is a sort of "free trade zone" along the border. The Mexican government wisely realizes that people who live right on the border will probably buy vehicles and lots of other stuff in Texas and New Mexico. Rather than try to tax and/or track all of that, they just set up a sort of secondary border beyond which you actually do have to have the permit.
Right before this check station we stopped because Tony's KTM had hit reserve earlier than expected. This might have been due to some top speed testing that Gustavo carried out on a long straight section of road.
In any case, Tony had a siphon, and we transferred some gas from the miserly DL650 to the gas-sucking KTM
We ate lunch in Ascension at El Dorado. Our first taste of authentic Mexican cuisine on the trip, and Tony would claim that they had the best salsa of any meal for the whole trip.
We arrived in Nuevo Casas Grandes in mid-afternoon and checked into the Hotel Pinon.
