Welcome to the TPP series, another little exercise from the warped mind of qbee. This is one of 15 caches, each of which may, or may not, contain a code letter. When one has found all 15 caches, they will have obtained all the information they need to solve the puzzle presented by the Bonus cache for the series, #16 TPP Bonus
This cache is not at the posted coordinates. However, at the posted coordinates one will will find instructions that allow them to locate the final container.
