Two weeks ago in Maui at the visitor center at Mt. Haleakala a distraught young woman came in saying she had dropped her wallet somewhere between the visitor center and the peak. When she went to the women's bathroom in the visitor center to check if she might have dropped it there, she found someone else had forgotten their iPhone by the sink.
Within a few minutes an older couple walked into the visitor center and said they had found a wallet on a hike but had lost their iPhone :-)
Two individuals each finding the others lost item was pretty karmic!
