You gotta love digits of pi, well ok at least I do 
There are so many cool things to be done with pi, how to figure out the digits of pi and more.
I remember when I was in high school about 10 years ago I saw a news report on a kid that won a Digit of Pi reciting competition. He won.... but stopped not cause he messed up or forgot digits of pi but because of pure exhaustion of reciting back the digits of Pi. He physically could keep going in speaking the digits of pi, he knew more but just could at that moment. I don't remember how many he recited but it was A LOT!!!!
I used to know over 100 digits of pi but that isn't going to help me or you with solving for the final
- To find the North Coords go to the 24,473,811 Digit of Pi (not including the initial 3) and use the first 7 numbers to gather the north coords.
- To find the West Coords go to the 5,771,074 Digit of Pi (not including the initial 3) and use the first 7 numbers to gather the west coords.
Difficulty is for the solve, actual cache is a very easy PNG with a FTF Pathtag Prize for the FTF.
