El Paso, TX to San Diego, CA

 After seeing snow capped mountains in Lincoln National Forest east of Alamogordo, NM I decided to take the most southern, warm, and probably the most boring route through NM via route 9.  Route 9 parallels the US-Mexico border and is used mainly by the Border Patrol.  There really isn't any other reason to be there as far as I could tell.  There are a couple small old railroad towns, Columbus and Animas, but not much else except a couple hundred miles of dust and the desert.

The lonely, windy, dusty Route 9 through NM, just a couple miles north of Mexico.  For about 200 miles the most exciting thing is crossing the Continental Divide.
