Remain calm!

I thought the Evacuation Route signs on Washington Street at Forest Hills and on Hyde Park Avenue in Cleary Square were confusing enough, what with them pointing in two different directions to get out of the city when the Big One hits (and STILL without answering the vital question: What the hell do you do when you get to the Dedham line?). But Subway Knitter takes a photo of a three-way Evacuation Route sign at Mass Ave. and Washington Street in the South End.
