(Courtesy of Irene Middleman Thomas/Special to The Denver Post) Just more than a four-hour drive from Denver or via a one-hour direct flight, there is a place that defied my expectations in a BIG way. Happily, on a recent visit, I discovered that Casper, Wyoming, is a delightful, diverse, happening, Western-feel town with a hefty dose of sophistication. From the moment I entered the airport (just one baggage carousel!) and saw the life-sized bison sculpture, I felt that “cowboy” vibe, and gave in to a selfie with it. Casper, with about 90,000 residents in its surrounding county according to the Casper Official Guide 2024, is Wyoming’s second-largest city after Cheyenne.
