When we moved into our 85-year-old house the neighbor, who knew the family for years, asked us if he wanted us to have him come into our yard with a metal detector. When we asked why would we want him to do that, he said that the couple use to hide wads of money in coffee cans and bury them in the backyard because they didn't trust the banks back then. We told him, "No Thank You." We've never come across any cans of money, but seeing how the neighbor knew about it I wouldn't think the backyard would be a safe place to store your savings. Dugh.
