Old Mexico’s Rancho Mababi is a land forgotten by time—one of few remaining wild places on earth where you can experience pure solitude. Prospering among its rolling desert foothills and towering, aggressive mountains is a thriving population of Coues deer. This diminutive whitetail subspecies, often called the “grey ghost,” is notorious for eluding the most dedicated hunters. Its small stature, shy nature, and the broken, brushy terrain where it calls home, make the Coues deer one of the biggest challenges in all of whitetail hunting. Your best chance of finding a mature Coues buck is to spend hours behind glass during the rut, picking apart every square inch of rugged ground to find a prowling buck on the move.
