Prime, I know this is not directly related to your question of whether contracts are needed (I still think they're not), but as to your type hunt: "Cache stories" are a dime a dozen. If I had a dollar for everyone who's convinced they know where a stash was buried, I'd be rich. Sure, go ahead and look. But just be aware, that stories get embellished over time, and you sometimes have to treat them with a grain of salt. After 30+ yrs. of this, I've gotten to the point that whenever I hear someone saying they know where a treasure might be buried, I don't put much stock in it. Unless it's first-hand knowledge, or other such primary source info, I won't chase too hard. Whenever it boils down to "someone told someone, who told someone, who told someone, blah blah blah", I don't get too exited. Been there/done that too many times.
