CACHE @ REI @ MOG Multi-Cache

Go to the coordinates posted at the top of the page, look down at your feet and see how many feet above sea level they are. Don't rely on the altimeter in your GPS. You can cheat and ask the employees in the store to help you but if they look at a button on their vest for the answer you'll end up with a number about a hundred feet too low. The answer is at your feet, really.

Walk straight into the store and buy some small cache trade goods. This is entirely optional, but the cache is too small to hold a lot of our usual trinkets. The cache is larger than something like a magnetic hide-a-key container microcache, but still smaller than my usual ammobox cache container.

Calculate the final coords using the altitude you found in step 1, then exit the store and proceed to the nearby final cache location.
The cache is at N34° 03.ABC / W083° 59.DEF

With

A = 3rd digit of the altitude
B = 1st digit of the altitude times 2
C = 2nd digit of the altitude times 3
D = 4th digit of the altitude
E = 3rd digit of the altitude divided by 2
F = 2nd digit of the altitude

Step 4 - the cache

No lockpicks, hacksaws, screwdrivers, or other implements of destruction are needed to access the cache. You can even take the cache container back to your car and figure out how to open it at your leisure. Make notes so you can reassemble it the same way. Due to past plundering it is currently a log book only cache. Please be very sure to place the cache back exactly as you found it.

The cache was placed with the knowledge of the store manager John Provost, who is willing to help you if you're hopelessly lost. Contact him if you are in the slightest way tempted to use any of the tools listed above. Thank you John!
