The clues are all accessible to the public, there is no need to go through security and into restricted areas!
For those who are planning a trip to Calgary for whatever reason, I suggest grabbing the clues to the coordinates while you're there so you will not be disappointed to find the final location is too far for you to grab it before leaving.
Cache contains a pencil, log, and a stamp for letterboxers; please do not remove the stamp! Please bring your own ink pad.
Solve to find the final: N 51 08.ABC W 114 00.DEF
The posted coordinates are your starting point, journey up to the second floor and locate door number 7. From there you won't be far from the UPS store.
When you arrive at the UPS store, there are a set of mailboxes. The boxes are divided into 6 panels containing a certain number of boxes per panel. Locate the correct box number to solve for the final. For reference panel 1 is the upper left panel.
Third panel clockwise, row 2, column 2. Reverse last 2 numbers for AB.
First panel clockwise, row 1, column 4. Last number is C.
Fourth panel clockwise, row 1, column 5. Last number is D.
Sixth panel clockwise, row 3, column 5.Reverse last 2 numbers for EF.
