PUBLIC LETTERBOX: This geocache is one in a Hybrid Letterbox series associated with U.S. Post Office Buildings. Posted (like in Post Office) Coordinates are on a public sidewalk outside of, across the street from, yet in view of, the Post Office Building (not collection boxes). Final Coordinates are in a public place a short distance away and are visible as a Waypoint for those who prefer not to follow the Path Description.
BONUS: Be sure to look for the Letter Alphabet Code if you want to complete the Bonus GCAHV69.

PATH DESCRIPTION: You as Geocacher will follow the path of a mailed Letter from the Post Office to your Final destination address. You may bike, bus (#221), drive, or walk (all at your own risk, of course) from the Posted Coordinates about 1.1 miles to the Final Coordinates. Go on N.E. 8th Street West. Go straight through 156th Avenue N.E. traffic lights. Turn Left or South on 148th Avenue N.E. traffic lights. Go on 148th Avenue N.E. to the Final Coordinates on Left or West.
LOGBOOK INSTRUCTIONS: This Letterbox was published on Dec 25, 2023 associated with a nearby geo-event GCADWPT "Chinese Food on Christmas Day 2023". Thus, the Logbook (Santa's "Naughty List") for Geocache finders is inserted into a red Envelope (as Mail addressed to Santa) in the geo-container.

LETTERS TO SANTA HISTORY: "Pictures, poems, and illustrations of St. Nick— particularly Thomas Nast’s 1871 depiction in the widely read Harper’s Weekly magazine —sorting letters from “Good Children’s Parents” and “Naughty Children’s Parents”— helped spread the idea of sending Santa mail. Nast is also credited with popularizing the idea that Santa lived and worked in the North Pole — for example, with an 1866 illustration that named “Santaclausville, N.P.” as his address — giving kids a destination to send Santa’s mail. The use of the post office to contact St. Nick began as a particularly American phenomenon. Scottish children would shout their wishes up the chimney, while Europeans simply left out stockings or shoes for the gift bringer." The Smithsonian Magazine, Dec. 3, 2015.
BLOCK STAMP FOR LETTERBOXERS: A Block Stamp (not a Postage Stamp) is provided for you to stamp only on your own letterbox material. Do not take this Block Stamp. Please bring and use your own Ink Pad as it is not provided. The Block Stamps in this postal office series are of Puget Sound Sea Life (Vie Sous-Marine) (Vida Marina) such as fish, dolphin, crab, starfish, turtle, octopus, etc.
