Sadly, I've had to archive several of my favorite caches. I loved them all, but they had to go. One of the locations is still usable (with a minor modification), so I decided to place a new cache there. To find it, you can either go check all of these archived cache locations or solve this simple puzzle. I suggest solving the puzzle. 
The cache is hidden at N37 14.ABC W121 57.DEF.
To solve for the final coordinates, match the cache with the reason it was archived. You can find all of the answers in the logs.
You can validate your puzzle solution with certitude.
A parking waypoint will be provided with the Certitude solution. Later days, my old cache buddies! I'll miss you all.
Congrats to PAVEIT on the FTF!
