The Bradley enters the South Hills neighborhoods. Sarge opens the hatch for a look around in the open air and sees more barricades and piles of corpses. Some of the barricades apparently held, some were overrun. Either way, it did not matter. Even if they held, Infection was everywhere, eventually making barricades meaningless.
Awesome book! If you haven’t read it yet, buy it!
