The subname for this cache is " Find the Sequence ". You will find a pull off at ground zero that is literally 15 feet from the cache. At ground zero, you will have to solve a semi-challenging field puzzle. Once you have that 'ah-ha' moment, you will soon have the combination to the lock in hand. The ammo box contains SWAG for the kids and the logbook.
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.
