OMG, I hope someone turns it in for you.
We put our name on our stuff like that. I tell ya what, it is not the people who find it I worry about as much as who it is turned in to at lost and found. Sometimes I wonder if they keep the stuff, but I am sure it goes both ways.
We found a wallet one time on the River raft ride once in the AK and yelled who lost a wallet, and made them describe it first. Sure enough it was theirs. He knew how much cash, name and address on ID.
Hope you get it back.
