I found "Riverside 1 - Maisie's Run" (GC3JWWG) today. This trackable, listed as part of the cache's inventory was not present but the owner's known that for more than a year (see la froggy's log of last May). If only there were some way of marking a trackable as missing. http://support.groundspeak.com/index.php?pg=kb.page&id=152
