The challenge was to recalculate the coordinates and remember how I solved the last part two months ago. I had some help with my Mom on the French back then.
digitalfish and I were working on it based some quick math and retrieval of my notes. We were stopped for a minute when we entered our new final coordiantes and saw them to be -- 60 feet away! That's some nice navigating there!
Nazgul made the find. Interesting cache in many respects, thanks.
