You might then get a chuckle out of another bit of Wyoming history old and recent: When America's silent film industry was in its infancy the Charge of the Light Brigade, directed by J. Searle Dawley and starring Benjamin Wilson, Richard Neill and James Gordon was shot in 1912 near Cheyenne at Pole Mountain and the Terry Ranch south of Cheyenne. The production used the U.S. 9th Cavalry [and it's Black Buffalo Soldiers] from Ft. D.A. Russell [now F.E. Warren AFB] as mounted extras.
More recently: The 1997 science fiction film Starship Troopers used Hell's Half Acre, located about 40 miles west of Casper on US 20/26, as the hellish giant bug-infested planet Klendathu. I suspect that CGI animation was used to produce the giant bug extras, but you never know: the makeup crew may have repurposed a few of the local bison.
Oh, and Smile when you say that, pardner.
And yet they film Longmire just up the road in right here in New Mexico. ;-)
