We vacationed in Colorado for decades, starting with my folks in my early years and then with my wife and sons since 1976. In all those years of being up there, I never saw Rocky Mountain Bighorn Sheep. Then, in 2010, while doing a road trip through Colorado with the wife, her oldest sister and her husband, we encountered these along the Arkansas River and Highway 50 west of Canon City, CO. There were five of them, but I was only able to get four in the same picture.
In Scott City, KS, there is the El Quartelejo museum that houses various things about the area and the fight at Punished Woman's Fork. Among the artifacts was a good set of old pistols that were created by Colt.
Clicking on either of the two pictures above will take you to those images at my Smugmug site. Then, one can click on the "X" in the upper right hand corner to see the rest of the photos in that folder, thus, one can then see the rest of the guy's collection of commemorative Colts.
