I have them on my land in Lyman and Tripp Counties. Generally, where there is old unbroken grassland or a prairie dog town within a couple miles and of course the draws is where I see the most. I usually let them live unless someone with me wants the rattles. It is always a thrill when you come on one or some as sometimes in the fall there are more than one as they are near their denning areas. I like the thrill as it reminds me of when I've hunted Africa. Though, maybe not near as dangerous.
