The first thing I noticed about New Mexico was the immediate reduction in the speed limit. In Texas, when the highway is in good condition, and the conditions are favorable to higher speed limits, it's not uncommon to find 75 mph maximum speed limits on roads some might think is too fast for conditions. Whether that's good, or bad, isn't nearly important - in my opinion - as allowing those the opportunity to cover the same distance in a shorter period of time. The 65 mph speed limit was way too slow in my opinion.
The long highway had power poles on the south side of the road, and at least every other pole had a bird nest in the crossbar. The appearance of the nests reminded me of those made by crows in my part of the woods. A little research by my wife, and the only birds to be seen during the drive, made me certain we were seeing the work of ravens. At first, I thought they were crows, but they were larger, as were their nests.
We stopped for my wife to take a photo of one in its nest. Unperturbed by our intrusion, it just watched as she got out and took the photo.
