I have not yet participated in any letterboxing activities, but I am a
avid "geochacher." (See www.geocaching.com). I'd like to give it a try,
but can someone tell me is there anyway to determine if the posted
listings are current? I don't particularly want to spend an afternoon
looking for a box that does not exist anymore. On the Geocaching
website, finders post the date of their visit, so it is easy to
determine if the site is still active. Thanks.
