Hints at geocaching.com are "encrypted"
with ROT13, where each letter is shifted 13 characters to hide
the text. This is not encryption. This is obfuscation. Figuring
out such hints is (as ROT13 is intended to be) trivial. There
are other forms of encryption that are much harder
to break, however...

You may find this calculator useful, although any high-precision
calculator (such as the Windows desktop calculator app) will
do.

Cache is a 180mL Lock&Lock containing a log book and a
pencil. It's small, but does have room for some goodies. Good
luck!

I can't say I expected to be able to solve this puzzle on my own. I spent hours upon hours reading over RSA encryption, fiddling with the numbers... doing everything I could think of doing.
Yet I still lived up to my expectations of being unable to solve this on my own  . After many fruitless hours of toiling away on it, I called out to friends via the interwebbing, and after much waiting (and a little more toiling myself), someone came upon the solution. Then again, the way they explained it to me made a BIT more sense... but not much .
In either case... with the coordinates in hand, I was primed to hunt down some cache. Unfortunately, after work today I had several prior engagements that couldn't me migrated or worked around. Hence, I had to wait a bit... until about 9:15 pm. The sun had just set, and the light was waning quickly. But still... off I set. I arrived at about 9:30, and quickly set to work hunting. It took me several minutes however, since I was... shall we say... looking incorrectly height-wise . But... I prevailed.
The good thing about doing a cache this late is that there's like... next to noone around, so avoiding drawing attention or prying eyes was quite easy. Thanks for the cache, and stretching my brain muscle more than it's used to being stretched... even if I did reach it's elasticity and needed some help to go the last few millimeters .
Took: Nothing
Left: Logbook entry and chainmail ball
