When Sandy's storm surge flooded New York's subway and split the city into its island parts, normal commutes were washed away. City-mandated restrictions prevented cars with fewer than three people from entering Manhattan to try to limit vehicle traffic. So New Yorkers took to new modes to get around. HopStop, the transit trip planning website, reported a 1,300 percent spike in searches for bus travel in NYC and an 800 percent jump in non-train searches compared to the previous week.
And then there were bikes.
On Thursday, the NYC DOT counted 30,000 cyclists riding across the East River bridges, more than double the normal 13,000. Though there's no official count for within Manhattan while the power was still out downtown and subways were halted, this audio postcard of a ride around town shows how Sandy created a mini-bike boom -- and a pop-up culture of cycling harmony.
