K is for Kangerlussuaq  LbNA # 62589

Clues

This one could also be considered a Scattered Guardrail.

Kangerlussuaq is the main international airport in Greenland. There is one other, smaller one!!!
When you exit the airport building, look for the Mamartuliat Deli in the whiter building. Left and beyond this is the Polar Lodge. Facing that, look for the car plugs and guardrail in front of you. This micro box is in the post below the 2nd plug from the left. There is no ink.
The number of people around will probably depend on the size of plane you came in on but be discreet anyway. Also, what you hear about mosquitoes is true. I got 4 bites planting this box and all of them were through my clothes. At your first opportunity you might want to purchase a mosquito head net. They definitely help.
