To qualify for the final, you must first find and log online, just one each of ELEVEN different cache types that were hidden over ELEVEN different years and were placed by ELEVEN different cache owners. (the new "Challenges" do not count)
As with most challenge caches, you are free to sign the log at any time (on or after 11/11/11), but you cannot log a find until you've completed the challenge, that is the date of your find, not the date you signed the logsheet.
The cache is at the posted coordinates. The ELEVEN different types may include any cache icon listed by geocaching.com (active or archived). However, benchmarks, waymarks and challenges can not count as one of the ELEVEN types for this challenge.
Please include in your find log a list of your ELEVEN qualifying caches, the ELEVEN qualifying cache types, the ELEVEN qualifying cache owners and the ELEVEN qualifying dates of those caches to demonstrate compliance with the logging requirements and your obsession with the game.
Note that this cache has been enabled more than ELEVEN days in advance to allow folks to work their way up to a potential FTF on 11/11/11. Therefore to keep this fair, you must include one find on a cache that was hidden on or after 11/11/11.
By the way, I did manage to mention the magic number, ELEVEN times in this description.
