This cache IS NOT located on base property. Starting coords were chosen only for fun. Cache is within ~600m of starting coords.
If you find where I was standing while taking this picture, then you just have to look down to find the cache.
On a side note: there are a few papaya trees around. I'm sure they belong to someone. Please leave them alone.
In case you need them, see hint for the last digit of the final northings and eastings (in DM format). This is, in and of itself, a clue how to extrapolate the coords.
Congrats on the FTF, EverydayExplorers!
