At 5:24, mhowardkarp tweeted from Hyde Park:
Just saw a woman jogging naked and barefoot on the sidewalk. At rush hour.
A few minutes later, Boston fire crews responded to the West Street bridge over the Amtrak/commuter-rail tracks for a report of a possible jumper. Crews didn't find anybody, but did find the naked woman back by Hyde Park Avenue, where they got her into an ambulance for evaluation.
