The cache is at the posted coordinates. You may find it anytime and post a note, but you must complete the assignment described below before you can log it as a find.
Your assignment, if you choose to accept it, is to find at least 29 caches on the 29th of any month (any month with fewer days, not possible); all qualifying finds must be made on one 24-hour day. You must include at least 3 different icons in your quest. Difficulty rating is based on the travel for finding the qualifying caches. Cache is 1.5 stars.
You may not claim finding this cache for any finds made before February 29, 2012. You may visit the cache, sign the log, and post a note, but do not claim the find until you have completed the requirements exactly.
To demonstrate your achievement, you do not need to list all 29 of your finds, only the date of your expedition and the three required icon caches. The rest should be verifiable from your public profile.
The area is very public, so use all appropriate stealth. Best after hours.
