Coloradans don’t want another Vegas, but sports betting has a chance Anna Staver, Denver Post · September 23, 2019 at 3:17 pm When Colorado’s casinos opened their doors in October 1991, one establishment had a dirt floor and served beer from an ice-filled trough that horses previously used for drinking water. “Black Hawk still had dirt roads. There was no parking, and there was a creek that ran alongside the road,” said Judy Laratta, who worked in a Central City casino on opening day and now serves as the city’s mayor pro tem. “It’s a booming place now. It’s like a little Las Vegas.” Amendment 4 was sold to Coloradans as a way to save three gold rush communities from the brink of extinction while preserving their historic charm.
