In an unprecedented move, the city of Boston, in its entirety, is being asked to shelter-in-place, with schools and mass transit closed. Nearby Watertown, where police and federal authorities are searching for the Boston Marathon bomber who is still at large, is in lockdown as Friday's manhunt continues.

At this moment, heavily armed members of the military, assisted by local law enforcement, are going door-to-door in Watertown, searching every house, garage, and shed for bombing suspect Dzhokhar Tsarnaev. CNN indicates that 9,000 members of law enforcement are involved in the effort. A no-fly zone is in effect over the town.

Authorities have asked businesses to remain closed. According to the Boston Globe, all vehicle traffic is banned in that city. In order to conduct its operation, the police are asking the media not to film what officers are doing.

While Watertown is teeming with activity, its larger neighbor is eerily empty. At a press conference this morning, Massachusetts Governor Dsval Patrick announced that everyone in Boston was being asked to "shelter-in-place;" that is, not to leave the house or answer the door — an order that affects 625,000 people.

Leaving Boston looking like this:

Not that there's anywhere to go, or anyway to get there. Taxi service was suspended, but has since been restored. Amtrak service and the regional mass transit has been closed; in part, apparently, because authorities don't want crowds of people gathering together.

Schools are on a delayed opening, and extracurricular activities have been cancelled. The Boston Globe outlines other closed institutions, including most regional colleges.

Boston Police identify other towns with shelter-in-place orders: Watertown, Waltham, Newton, Belmont, Cambridge and Allston Brighton. In Cambridge, which lies between Boston and Watertown, singer Juliana Hatfield woke up to this notice on her door:

A resident in the area describes how he learned about the situation:

I got the emergency texts all night from MIT, and we had robocalls from Belmont PD telling us to stay inside, one just a minute ago saying town offices and buildings are closed.

Others who are staying in their homes in the area seem to be struggling to process the unusual scenario.
