Do You Measure UP? is the sub name for this cache. At ground zero, you will find the tool needed to see if you measure up to the task. A steady hand and just enough hight will allow you to obtain the combination to the ammo box at ground zero. Have fun and if you enjoyed this cache, I do appreciate when a favorite point is added letting other cachers know this was a unique and fun cache to visit.
The CO works out of his home, and should be available most times, so stop, knock and say hello if you feel like it.
