No, literally. The Post reports that employees at the U.S. Post Office at 2 Massachusetts Avenue NE are suffering from a leak located somewhere in the undercarriage of the old building which is causing brown stains on the ceiling and an overwhelming sewage scent. Yummy! Not content with attempting to overthrow one of the District’s busiest postal centers, the gaseous amalgam of odor is also attacking the Capitol City Brewing Company, also located in the National Postal Museum building. Attacking the mail is one thing; once our beer is threatened, something must be done. But just like The Fog, efforts to fix the atmospheric disruption will be convoluted: “embedded really strongly in the concrete,” the source of the scent can really only be reached by digging holes into the walls and floors of the 95-year-old structure.
