You know, every year I place these Delta Pi Caches, because I like the two greek letters Delta and Pi. However, I've been so busy this year that I was disorganized. After I placed this cache, I lost the numbers you'll need to find this cache. I'm sorry I lost them, but I have full confidence that you will be able to find them by throwing some darts. I remember enough to be able to tell you that I placed it on the island, the west (partial) coordinate is first, and that from the puzzle coordinates you will need to go 30° for 30 feet.
Again, I'm sorry that I lost the coordinates. Good luck!
As an aside, this is also the birthday of Albert Einstein and Billy Crystal.

You can validate your puzzle solution with certitude.
Note: As is letterbox tradition, you will need to bring your own ink pad. A black ink pad is recommended. And, I didn't add a pen so make sure to bring one to be able to sign the log.
For every three months that this cache goes unfound I will add an additional half star to the difficulty rating.
Congratulations to Nezzmuk. del2u, Dix1, Cheda and ratwaffles who were first to find this cache. This was a well-fought battle for this multi-layered Pi, and they all came back alive, only slightly wet.
And remember to bring your own pen because you don't want to have made the trip but not be able to sign the log.
