For some reason, I thought you lived in WY. Sorry!!!!!
Those particular pics are from SC MT just north of the Park. I lived in Manhattan (22 mi. W of Bozone) for almost a decade. I hunted the Elkhorns, Gravelys, Absarokas, Beartooths, Snowies, Pryors and a few other spots here and there. As a kid I lived in BLGS, and before that we were out in the SE by Fallon. Thought Terry was a big town!
Work has recently brought me up to Alaska.
I've never hunted "off" of horses, but growing up I was around them a lot, and often my chores included taking care of them. Not pets, or even horses for hunting/packing, just working horses on ranches. There's a reason why so many ranchers have 4 wheelers. Though for moving stock, a good horse with a good rider is all business, and they are a joy to watch working as a team.
