For 2016 I decided I would try to place a series around the Pittsburgh area consisting of 81 caches, one of each of the 81 Difficulty/Terrain combinations. I have seen another series like this in the Virginia Beach area and thought it was a good idea. The series will consist of all 81 combinations as well as different cache types.
You are looking for a well-hidden purple bison tube. Coordinates should be pretty good. Keep in mind the D/T rating. No hints on this one...unless you already caught one ;-). This is a bring your own pen cache, no room for trackables or a pen. You must sign the log for the find to count.
PLEASE REPLACE EXACTLY AS YOU FOUND IT!!
