We need to find a place with brick walls. Private schools, mansions, that sort of thing. Someplace with some interior walls that we can break up to plug the gaps in the main perimeter. Worst comes to worst we can make a run to a construction site and salvage what we need.
It had better be soon, though. They’re gonna start coming out of the cities any day now. The wind will shift and they’ll follow some trace scent in the air, and they’ll stream out from between the tall buildings like a flash flood. We’ve got to be ready.
