Cool piece in the San Francisco Chronicle on the expanding popularity of geocaching as an outdoor “adventure” sport in Bay Area parks:
Dave Grenewetzki, 52, was on bended knee, rooting through bushes in downtown San Rafael, and eliciting bewildered looks from nearby beauty-school students. With a global positioning system unit in one hand, he appeared to be either a tech-savvy bag man or an obsessed arborist. He was neither. He was digging for treasure that was hidden by his friend Don Forman, using only the treasure’s GPS coordinates – its longitude and latitude – and a clue: “Think about some of the old rock & roll music and the lyrics. You might get an Education.” Forman stood by, tight-lipped.
Although not a Pink Floyd fan, Grenewetzki finally found the treasure, a film canister inside a loose “brick in the wall” behind the bushes. Forman had hollowed out the brick in his garage with a drill bit, and rolled paper inside the canister to allow those who found it to record their accomplishment. “Don, you need to get a life, man,” Grenewetzki said. “You are one sick guy. ”
