The cache is not at the above coordinates! Don't go there!
A friend of mine, Julie, had this idea for a puzzle cache. She has a few crazy ideas that I don't think that'll work, but I liked this one the best. Not exactly what she had in mind, but I think she'll like my rendition of her idea. If you like it please give my cache a favorite point. As usual I probably gave too much away, just one of those things! Solve for the last three of N and W. Good luck!
