The brush country of south Texas is a world all of its' own. Near Del Rio, it merges with the Chihuahuan Desert and shares many flora and fauna with its' western neighbor. On its' northern reaches, it rises to become the Texas Hill country.

The brush country is characterized by low, thorny scrub, mesquite thickets, and cactus of various types (all of whom have more thorns than the traveler would like), hard soil, and wildlife of all kinds. Beautiful country, but hard on humans. The scrub is low but the sunlight and heat are high and shade fugitive.
