With Brain & Pinky, Eikenhofjes and Xizat I travelled 11 days through the USA to find some very old caches. On our 5th day we found some caches in Seattle and visited Head Quarters.
This cache was at the specified coordinates (with the artwork of the same name), but we had to do a little puzzling to get it open. When we figured out the system, Brain quickly opened the box.
Thanks and cheers!
