The Ringling Bros. and Barnum & Bailey Circus is back at the Verizon Center March 18-22, and with it comes the annual parade of elephants through the city. The route for the animals will begin on Tuesday, March 17 at Garfield Park, then head north on 4th Street SE to Stanton Park, then west on Massachusetts Ave NE to Columbus Circle NW, then finally toward the Verizon Center via E Street NW, 3rd Street NW and G Street NW. If your home or office is near the walk route, tentatively mark your calendars for a 10 a.m. pachyderm parade start time (subject to change, call the Animal Walk Hotline, 1-866-683-3670, for updates that morning). Since the elephant walk is happening on St. Patrick’s Day this year, the animals are indeed expected to wear green and bring along their own bagpipe player.
