How do you like your pi? There are lots of different kinds, and this one is Mud pi.
The cache is NOT at the listed coordinates.

Every year on March 14, the date is the same as the first three digits of pi. But it doesn't stop there. Online you can find the first one million digits of pi, but we don't need that many. In fact, we only need the first fifteen. Yes, that's a hint.
It should all be clear now, especially after you have all the Mud pi.
