Doesn't really look like an official document but that is the city administrator. All the offices are closed right now but I called down and got somebody at the SO, and they didn't know anything about it, but they did allow they're the last to know about anything the local government does. If you find it, yeah I bet they know a whole lot about it. I hope you find it, but I can't figure out why you're makin a big publicity deal about it. I don't even know why you would have to make a cut with local government, as it's not unclaimed property, and the owner has given you (and everybody) permission to go retrieve it. Same as if I left my sleeping bag at a state campground, told everybody where it was, told them to go find it, I don't see where they would have to make any kind of deals with the government. I may sound a little negative, but I am cheering for you and hope for the best.
