This was a county in Virginia prior to the apocalypse.
Walkers arrive at the labor site and a commotion ensues. Jed panics and lets go of a rigging rope, allowing a giant log to pin Aaron to the ground. Daryl yells to the crew to lift the log while he double-knives the walkers around him. They lift the log but Aaron's arm is crushed. Daryl carries Aaron to the camp as Rick and the others arrive to hold off the walkers. Rick shoots a rope restraining a log pile, loosing an avalanche of logs to crush the remaining walkers.
