Mule Deer are one of the most exciting and beautiful big game animals in the world. Mule deer originally received their name because of their large ears, which resemble that of a mule. They have incredible hearing, great noses and excellent eyesight. Their current range is very large, encompassing the Western United States from the Great Plains to the westernmost states and from northern Mexico to southern Canada. Mule deer hunting might well be the crème de la crème of big game hunting.
