Learn how the game began--in a new foreword by its founding father, Dave Ulmer--and discover how to: select a cache listing and begin your hunt for the treasure; buy a GPS receiver and use it to navigate to the cache; create and hide your own cache...

A local radio station is holding the Great Detective Race, and the Boxcar Children have entered the contest! They solve riddles and search all over town for clues leading to the grand prize.

Believing his long-absent father is missing and leaving clues behind through geocaching, Zig, thirteen, relies on his love of electronics, a garage sale GPS unit, and his best friend, Gianna, to search for answers.
