Reminds me of my time at Colo School of Mines in Golden, CO back in the late 1970s. We would routinely do the short tour straight to the hospitality room for the 2-beer a day limit of 3.2% alcohol Coors, which was legal for 18 year-olds. I don't think their brewing process fully removed the mine tailings out of Clear Creek, though. I'm pretty sure it does now.
