Because the zombie-deer apocalypse is nigh, everyone needs an underground deer shack. Atlas Survival Shelters of Montebello, Calif., will build you one made out of a shipping container or corrugated pipe. The one pictured above, is decorated in a deer-hunting theme and doubles as a hunting camp bunkhouse. This particular corrugated pipe model is 10 feet by 51 feet and costs somewhere in the mid-70s uninstalled.
