For me it is Camelback Cache http://www.geocaching.com/seek/cache_details.aspx?guid={16A592C2-52D1-4707-BDA8-11A213D83B34}.  Went after this one in August and it was 110 by the time I gave up.  I still have it on my watch list even though it has been archived.  The only bright spot was that no one ever did find it.

The listserv has been amazingly quiet lately. Here's a question I'll toss out in an effort to stimulate some conversation.
 
If you've been caching for awhile there is probably at least one cache you tried to find several times without success.  You REALLY wanted it but it eluded you. Others have found it.  It now may be archived and you'll have to live with your failure forever.  One that comes to mind for me is Ya Skala.  What is yours?
 
Any takers?
