I'm not into letterboxing but yesterday when I was on the Kennebec Rail Trail, near Mapachi's Abby's Cache, I saw a Tupperware container out in the open, box here, light green top there, and a rubber stamp and ink pad elsewhere. Does anybody know who that might have belonged to? It's by the bench on the main trail before you turn to go to Abby's Cache. I thought the ower might like to retrieve it.
