The South Wall (Visualization of a fictitious project by J. F. Bautista)
If you have time and its a sunny day why not take a walk down to the South Wall starting from the the Gulf of Mexico to the Pacific Ocean, traversing a variety of terrains.
The total length of the continental border is 3,201 kilometers (1,989 mi). From the Gulf of Mexico, it follows the course of the Rio Grande (Río Bravo del Norte) to the border crossing at Ciudad Juárez, Chihuahua and El Paso, Texas. Westward from El Paso–Juárez, it crosses vast tracts of the Chihuahuan and Sonoran deserts to the Colorado River Delta and San Diego–Tijuana, before reaching the Pacific Ocean. (Wikipedia)
