Wynken, Blynken, and Nod one night
Sailed off in a wooden shoe--
Sailed to find a crystal light,
that went in and out of view.
"Where are you going, for what do you look?"
The old moon asked the three.
"We've come to find the prized logbook
That was hid here so expertly.
Pens of silver and gold have we!"
Said Wynken,
Blynken,
And Nod.
Posted coordinates are for the dock where you, along with Wynken, Blynken, and Nod will set sail and begin your journey. There you must acquire the number of benches AND light fixtures on the dock. Add them together and subtract 3. Once you acquire that number, head towards the sunrise on the sunrise.
Use that number for what traffic light you will turn left at to get to the final. For example, if the number is 2, you will turn left at the 2nd signal.
Good luck and happy caching!
