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 Final Coordinates. You may bike, bus, drive, or walk (all at your own risk, of course) to the Posted Coordinates. Parking is limited. Then you have about 0.2 mile to the Final Coordinates. Go North on 4th Avenue. Stop where 4th Avenue turns into 5th Avenue; This point marks the Public Trail TH (see Blue Sign). Turn Left or West on Public Trail. Go past the Dog Waste Station to Final Coordinates on the Right side of the Public Trail.
LOGBOOK INSTRUCTIONS: This geocache's Logbook represents miniature folded Postcards that is inserted into the geo-container. Each geo-finder marks one Postcard. Postcards align with their recent attention from Geocaching. For example, the Adventure Lab app creates e-Postcards, which may be e-mailed, for all AL sets completed. Another example is Geocaching HQ announcing that the first Postcard Day is October 1, 2024, when an e-souvenir will be given.

POSTCARD HISTORY: The first postcard was posted on July 14,1840 to Fulham in London. The hand-painted design on the postcard is an image of post office clerks sitting around a giant ink well.
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.
