For more than a decade after they moved into their house in Neenah, Wisconsin, the Zwick family knew they had a Cold War bunker in their backyard.
It was not until 2010 that anyone thought to open the heavy steel hatch, climb down the ladder and explore the 8-foot-by-10-foot chamber that the home’s previous owner had built to protect his family from a nuclear attack.
Floating in five feet of water that had seemed into the bunker were sealed U.S. Army boxed packed with all of the supplies a family would need to survive two weeks underground.
‘We assumed it was just this empty space,’ homeowner Carol Hollar-Zwick told the Appleton Post-Crescent.
The boxes, old military ammunition crates, contained markings that suggested there might be explosives inside, so the family called the local branch of the Bureau of Alcohol, Tobacco and Firearms.
Agents opened the crates to find… Hawaiian Punch.
