Lets think about this a different way. Perhaps the milk run was could be viewed as comprised as two milk runs patched together as one - one from Denver to some point, X, that it would make sense to stop at Colorado Springs and Pueblo en-route to such that X is also a point where it would make sense to depart from flying towards San Antonio via Santa Fe, Albuquerque, El Paso, Carlsbad, Hobbs, Midland/Odessa, an unknown point, and San Angelo. If so... the larger Las Vegas (NV) would make sense.

Now, we must think what's between Midland and San Angelo. My guess is Big Spring (but it could be Abilene).

Would the complete run be?

Denver

* Colorado Springs
* Pueblo
* Las Vegas, NV
* Santa Fe
* Albuquerque
* El Paso
* Carlsbad
* Hobbs
* Midland/Odessa
* Big Spring
* San Angelo

San Antonio
