I found $25 in change along my regular route last week. All in one pile, like it was purposely left. Hmm.
Last year I found a working Net-book, picked it up, turned it on, found out who it belonged to and returned it. Apparently the owner had a flat tire and had to remove everything in the trunk (including the net-book) to get to his spare tire. Assembled the spare, put everything sans the net-book back in the trunk and drove off. He was grateful I took the time to stop, pick it up and check for a sign of identification
