For those who will find this interesting....
I was at NMSU when Jim Reilly established that mark, I believe it is on the "Horseshoe". Jim was the head of the Dept of Surveying, College of Engineering.
By the way the control at the Las Cruces Intl Airport is really good.
If I were in Las Cruces I would whole-heartedly support a new coordinate system based on an LDP. But the author hasn't mentioned the imminent NAD2022(?) roll-out at all. I think that's a mistake.
