Hey, Whitebird. That looks a lot like a desert muley from the Ironwood Desert..... I was about to guess it came from Palo Verde, Ca., but the tag doesn't look like a Kalifornia, D-12 tag. So, Arizona, Mexico ? Very nice buck and rifle. E (that stands for Eremicus as in O.h. Eremicus, the latin name for the Burro Deer of the Ironwood Deserts)
