This Challenge Cache was created to celebrate the 20th Anniversary of geocaching.com in year 2020 with its 20,200 Community Celebrations around the world. One could say the world is one community as geocachers easily connect with new geopals whereever they travel on the planet Earth. This cache is dedicated to you, the Geocacher of the World, whose passion propels you to travel many miles by foot or by geomobile or by geoaircraft to get that Smilie as a Found.
This cache is located at the posted coordinates near, but not in, the SeaTac Airport, to give geotravelers ready access. Closest vehicular intersection is S. 182nd St & International Blvd, at exit from the airport. If in a vehicle, park safely in nearby hotel or restaurant visitor parking, then walk safety to lamppost number "5".
In order to qualify for this Challenge Cache, you must have found ONE cache on the U.S. East Coast (states along the Atlantic seaboard, plus Puerto Rico and the Virgin Islands) and ONE cache on the U.S. West Coast (states along the Pacific seaboard, plus Alaska and Hawaii).
