We hear he lost an arm in a freak run-in with tourists outside his apartment building on his way to work this morning. Excuse any bumps and wrong turns as we guide you through the wild ride that is the world of D.C. transportation…)

Metro to Suck Today: This might be a little late for those attending the 1 p.m. Nats-Brewers game this afternoon, but WMATA has officially warned its riders that the commute to RFK could be a little crowded. There will be extra trains and additional station managers, but expect delays.
