He headed north, staying on Swamp road as it changed names. When it dead ended, he took the right going straight north. Walkers were scarce at first, wandering aimlessly when sighted. They became more common as Garcia passed a commercial building. Perhaps two dozen or more (that could be seen) were gathered around this building parking lot. Garcia then passes over railroad tracks and enters a residential area. Single family homes on half acre lots are the standard in this area. Walkers abound here and hundreds are wandering around the neighborhood. They are attracted by the movement of the vehicles and begin sauntering toward the road where the group is travelling.
Further up the road there is another railroad track and Garcia crosses it into what looks like the downtown area. As he makes a turn onto a downtown street, the road ahead is covered with walkers. They turn their heads at the truck and begin moving toward it. There are perhaps a thousand of them. Garcia throws the truck into reverse and begins backing toward Amy in the Jeep.
