I have mused before that if I were a billionaire, one fun thing I’d want to do with my money would be to hold treasure hunts for the public. Every few or months or so, I’d hide a few million dollars in cash (or some similarly valuable prize) somewhere in America, then post a few clues online about how to find it (it might be hidden in the wilderness in Wyoming, or a forest in Tennessee, etc.)
What sort of legal liability would I incur by doing this?
Some that come to mind is that the land might belong to the federal government, or that if people died of hypothermia or shot each other while fighting for the treasure, I might get sued. What else would be illegal about this?
