This discussion got me to thinking about populaions along each route. Here is what I came up with with the current route(populations are approximate from city-data.com)...
Lamy, NM (Santa Fe) - 62,000
Las Vegas, NM - 14,000
Raton, NM - 7,000
Trinidad, CO - 9,000
La Junta, CO - 7,000
Lamar, CO - 8,000
Garden City, KS - 27,000
Dodge City, KS - 26,000
Hutchinson, KS - 41,000
-------------------------
Total: 201,000
If it rerouted on the transon, here are some possible stops and their populations...
Clovis, NM - 33,000
Hereford, TX - 14,000
Canyon, TX - 13,000
Amarillo, Tx - 185,000
Pampa, TX - 17,000
Woodward, OK - 12,000
Wichita, KS - 350,000
----------------------
Total - 624,000
That number only includes a few cities/towns along the way. Could be some good ones I missed.
