Durango Nature Studies put on it’s fourth annual bluegrass festival on Thursday evening at Rotary Park. The event was a fundraiser for Durango Nature Studies and the proceeds will help support the Durango Nature Center, environmental education, and other programs, said executive director Sally Shuffield. A few of the sponsors who helped out were Carver Brewing Co., Sunnyside Meats, and Star Liquors. Among those performing were Wild Mountain with Brad Bartlett, left, and Estella Moore.
