A long time ago, in a galaxy far far away... there lived a geocacher by the name of [Bi]ll. Bill loved solving puzzle caches, however he was very [Ag]gravated by one in particular. After completing the required puzzle, Bill realized that there were too many num[ B]ers! Naturally, [He] began using his reasoning skills to [Th]ink of a solution to this problem. "[O]h!" Bill exclaimed. "I can just email the cac[H]e owner!" A few hours later, he received an email back. "[Sc]an the numbers you got. There are two extras. Remember that 83-47=36 and 88-39=49. You can [ V]erify your answer with the checksum in the hint," it said. Bill immediately solved for the coordinates and [Ra]n outside to his car. Arriving at the GZ, he quickly found the cache and signed the empty log. "[Y]es! First to find!" he exclaimed. And that concludes the story of Bill and his geocaching adve[N]ture.
