If you were around in the ’70s and ’80s, you can now forget what you heard about Rock Springs and Green River, Wyo. They no longer deserve the notoriety of Wild West oil boom “Sin City” towns with more prostitutes than New York’s Lexington Avenue, and more bars than Las Vegas. Recently, while visiting both cities in Wyoming’s largest county, Sweetwater, I was pleasantly astonished to find swanky bistros with yes, even vegan offerings.
