With so many Forts around, you just know there must be spies everywhere.

See if you can spot any.

The cache is not at the posted coordinates, but your adventure starts there.

Once you have arrived at GZ seek something that will help you spy on the objects pictured.

Then use the following formula to obtain the true coordinates.

N 39° 36.ABC W 75° 3D.EFG

Good luck and have fun.
