From the posted coordinates, I hiked 2.3 miles get to where I hid the cache. Solve this puzzle to figure out where your actual destination is:
First, take the three numbers that begin with 7 from the other caches and discard the first digit (the 7) from each number resulting in three two digit numbers.
Add the smallest and middle numbers together and add 2 more to get xx. Subtract the smallest number from the largest and then add 8 more to get yy. Then plug those numbers here:
N 39 38.xx9 W 105 16.yy7
Oh, and bring your own pen.
If you found and logged one of the first six caches but don't have the number from its lid, send me an email with your cacher id and I will provide the number free of charge.
