Subway survivors: Rats will have outmaneuvered Sandy's underground floods.
Hurricane Sandy's storm surge pushes seawater into New York City's Carey Tunnel on Monday.
New York City's rats have arrived. In the wake of superstorm Sandy, residents of the city are soon likely to see them by the thousands, since the rodents have been driven from flooded subway tunnels.
When weather is drier, the rats seem to love living under the soil, and can dig deeper than water can seep. They could even have been safe in their burrows as the storm swept the city Monday. But many likely were out on the hunt for food.
