The longitude coordinate of the cache is E175°37.4x8. Alas the latitude coordinate is with the trackable. Which is here, at GZ, somewhere. Can you find it?
x is taken from the first character of its tracking ID. If the character is a number, subtract one from it. If it is a letter, add the digits of its position in the alphabet, then subtract one.
