Some people just can't get enough of puzzles or enough of Pi. It's especially for those people that this geocache is placed.
As you might suspect, this geocache is not to be found at the posted coordinates. Instead, somewhere on this page you'll find the digits for the coordinates where this geocache can be found. But of course, there are a lot of digits on this page - just which ones will give you what you need? You'll have to cherry-pick your way through this page to find the digits you need.
Happy π Day!
