WATERTOWN – A Wisconsin man who thought he found a cool piece of history was hanging on to a potentially dangerous find.
The Watertown man found a Civil War-era cannonball while digging in his yard last year.
He had planned to donate it to the Wisconsin Veterans Museum in Madison. However, when he called the museum this week, the curator told him to contact the fire department right away.
The Milwaukee bomb squad was called in to detonate the device because it still contained gunpowder.
