Geocacher Rest Area Mystery Cache

Every geocacher needs a good place to stop, eat & rest after a good day of caching.   At GZ you will find a puzzle hanging from a tree and a locked ammo box at your feet.....solve the puzzle...release the key and go grab and burger and fries... I am listing it a difficulty 5 because it took me a while to solve it...so for some...this may be a 1-burger sml fries and ice cream stop (done the first time) for others it may be a 3-burger, large fries and an ice cream stop (came back and solved it the third time around).  Good luck and have fun.  This was placed with the business owners permission.
