This is a challenge cache so it IS AT the given coordinates. You may find and sign the physical log and write a note online at any time, but you must meet the prerequisites before posting a “Found It” online.
To qualify, find 13 caches each pertaining in different ways to "Lucky" "Friday" "Thirteen/13"th, as follows:
At least one cache with the word "Luck" or "Lucky" in the cache name, but not "unlucky" nor any other word containing the etters "l u c k".
At least one cache with the word "Friday", the whole word spelled out, not abbreviated.
At least one cache with the word "Thirteen" or "Thirteenth" spelled out.
At least one cache with the plain number "13", not part of any larger number, but "13th" is okay.
At least three caches PLACED on a Friday the 13th of any year (regardless of the name of the cache).
At least three caches you FOUND on a Friday the 13th of any year (regardless of the name of the cache).
The additional three caches of your 13 qualifiers can be in any of the categories above after you've met the minimums for each category.
And just to make this more challenging, you must include 3 different icons among your finds.
No, this cache cannot count as one of your 13 finds. As with all my challenge caches, one cache that you place and maintain, or an event that you host, can substitute for any one of the requirements, but only one.
You can demonstrate that you qualify in any manner that is clear and available for me to verify.
The difficulty rating is my estimate of the difficulty in finding the qualifiers. The cache itself is an large-ish micro tube attached in plain sight. NOT on the back fence; don't go there.
There may not be safe parking at GZ; use your good judgement and maybe park at a better pullout further along this country road then carefully walk back. Watch for surprisingly fast-moving local traffic - don't push your luck!
