Welcome! You must be thinking about the hunt?
Below is the cover of the new book for 2016 - the Twentieth Anniversary Edition!
This edition focuses on the big parks, and as usual, it includes a lot of details that would only matter to a clue writer.
It also includes some cool aerial photos I took with a camera-rigged kite, a project that kept me busy for a couple years.
As always, you can order the book from me online or find me at the park.
If you like, I can send it to you with a good luck Map Guy signature!
