1) Upon arrival at the published coordinates, make note of the installation date of the new infrastructure
2) Format this date as “DD M YYYY”.
3) Translate this as “DD M YYYY” = “ab c defg”.
4) The cache coordinates are: N 41º 40.999 W (60 + ab)º (31.132 + cd.efg).
This cache is part of a series – its theme should be readily detectable.
There is a puzzle cache which completes the series. Collect clues from the log sheets from the other caches to solve the puzzle and determine the coordinates of the final cache. The FTF may find a prize in the final cache.
