We started the trench on the west side, and the city is to the west, and so far we’ve been lucky: most of the zombies have come from that direction. We ran out of gas for the backhoe three days ago, so we’ve been digging by hand. Right now we’ve got most of three sides all the way down to eight feet.
Inside the perimeter? Eight houses, a good-sized stand of trees, and some land to grow vegetables. We’ve been steadily bringing in building materials and supplies. It’ll have to be enough: odds are we’ll be here a long time.
