I used a nearby stump as a geocache location since March 2012, first as a Traditional, and recently as a Multi.
However, mrdsw and ducks66 had to dig through a foot of a Pack Rat's nest to find it. At my request, they moved the preform to another place and put some rocks on top of it. Rather than just updating the cache, I am Refreshing the Game Board and creating a new geocache.
