These coordinates correspond to locations in Colorado, for a total of 24 unique secret locations. The promotion, dubbed the DBC Explorer Challenge, requires participants to visit all 24 locations and take a photo in each spot to be eligible for the grand prize – free Denver Beer Co. beer for one year.
