If anoyone should ask....permission was granted to place this cache by the female manager of the store.
At GZ you will find an ammo box with a combination lock. There is an additional container attatched that holds a bit of a puzzle cache....figure out the puzzle and it will reveal the lock's combination. You will need a UV light for this cache. Easier if you sit in your car and figure out the puzzle.
I am making it a 2.5 difficutly because of the puzzle....for some it may be easier...and others harder...we'll wait and see.
