Write down or take pics of the letters and numbers on the inside of the lids of each of the 3 traditional caches.
Insert the corresponding numbers in for the letters of the MYSTERY CACHE coordinates:
N42 AA.BBB W071 CC.DDD
You will want to use the Welch Pond Trailhead to help guide you to the cache. The cache is an ammo box covered with natural camouflage taken from the surrounding area. Please be sure to cover it the same way you found it.
