While archiving our 2002 PURU Commemorative Cache, we found this geocoin. Since we're not going to be doing any caching in the near future, I've got some geocaching friends checking into whether there are lighthouse caches near their homes. If there are, I'll mail the coin to them and they will place it in the new cache. If not, I'll be contacing pdxmarathonman for his snail-mail address and return it to him.
Thanks for the very unexpected find!
