Wisconsin families makes unlikely backyard discovery

The Zwick family of Neenah, Wisc., got a surprise when they cracked open an old Cold War fallout shelter their property's previous owner had installed. Though decades of disrepair had flooded the shelter, air-tight containers full of survival gear now serve as a time capsule of sorts -- a stark reminder of nuclear tensions at the time and a look at the "preppers" of yore.

The Daily Mail reports:

'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.

'It was all of what you would expect to find in a 1960s fallout shelter. It was food, clothing, medical supplies, tools, flashlights, batteries - items that you would want to have in a shelter if you planned to live there for two weeks.'
