When a storm shuts the Sound, the ferry line at the terminal empties out and the island is on its own until the weather clears. Rapid Recovery Martha's Vineyard is built for exactly those hours in Oak Bluffs — plowing drives and lots, shoveling walkways and entries, sanding and salting the slick places the wind keeps refilling. Snow that lands wet and then freezes hard is the local specialty, and the answer to it is coming back more than once. Getting a family out of their own driveway on a morning when nothing else is moving is a small, real thing to do. Oak Bluffs and the towns nearby, whenever the weather calls for it.
