Avast ye, scallywags! Come sail here during daylight only. Ye can park on the street right next to the posted coordinates.
To begin yer quest, use yer eyes to look in the second tree from the intersection. There ye will discover the secret to opening the treasure chest. Then approach the porch along the walkway. There ye will find a cryptic container to manipulate. Each knob be either in or out, and then ye can open the door. Gently, please--I be a pirate, not a carpenter!
Take ye an imprint of me custom stamp, and leave the image of yer own if ye'd like. Regardless, let me know ye visited by marking the logbook. Trade some swag. Why not plunder a toy? There may even be a treat for ye nearby.
I've told the neighbors about this. Happy caching!
