I dropped them a note asking, politely, if they would move it along, and offered to swap it for a collectable, but non trackable geocoin. Since they are local to me, I might ask them to mail it back.
EDIT: Got a nice reply back from the family, and I guess the traveler was giving to a family member to head off to another cache... possibly just not logged in yet!
Thanks for the suggestion,
MrC
