Numbers - Lonely Cache Challenge Mystery Cache

I really love Challenge Caches.  I qualified for and logged quite a few this past year and now I am adding one for you to attempt. This one may be very easy or very difficult to qualify for.  This one might test your willingness to to where no cacher has gone before...or at least during the last year!
IN ORDER TO LOG THIS CACHE AS A FIND YOU MUST FIND AND LOG A GEOCACHE THAT HAS NOT BEEN FOUND IN AT LEAST 365 CONSECUTIVE DAYS BEFORE THE DATE YOU FIND IT. You may include a find prior to the publication date of this cache. You may include a cache that has never been found previously as long as it has been at least a year from the date of its publication. If a group finds a cache according to these rules, each member present for the actual find may claim the qualification for this one.
To verify your qualification for this one, please list the GC# of the cache you found which qualifies you in your log. If you use GSAK, there is a "LonelyCaches" macro. Once you have met the requirements, go find it and sign the log. The Difficulty and Terrain for this cache are a factor of the effort you will have to put into qualifying for the cache. The actual D/T for the hide would be considered a 2/1.5.
