My son was flying home from Kenya (he was in the Peace Corps) and left his journal in the seat pocket in front of him. He despaired of ever getting this back, but he phoned the airline and they had retrieved it. (Apparently they see all kinds of stuff.) So he got it back.

I put my full address on the first page of my journal when I start a new one. I've never lost one, but I feel good knowing that it could find its way back to me if I did.
