what you are talking about is simply an emoris ratsnake, or chocolate ratsnake, that happens to live in utah and colorado and places like that. it is not truly recognized as its own species. of course these are going to be small, due to lack of food, and warm weather. but you can get one of these and practice perfect husbandry like with any other corn snake and you will have a 5 foot monster too. but hey way to keep me on my toes i appreciate that.
