They're everywhere. That is what surprised me most. When I first heard about a newfangled treasure-hunting game called "geocaching"—a form of hide-and- seek using a handheld Global Positioning System (GPS) device—I pictured hiking to remote wilderness areas. I soon learned that dozens of the clev- erly placed containers, or caches, lie right near my suburban home.
It works like this: At the Web site
www.geocaching.com, enter a country, state, or zip code to open long
lists of waterproof caches posted by participants called "cachers." Some
300,000 hiding places exist worldwide, with more added every day. I
type in my zip code to find plenty nearby.
Latitude and longitude
coordinates measuring north from the equator and west from the
Greenwich meridian identify each within a few feet, and occasionally
riddle-like clues spice up the challenge.
Using a battery-powered
GPS unit (they sell for $100 to $1,000) and bringing my adventurous
12-year-old daughter along, I begin searching. Soon we're poking around
places we've never really noticed. We locate an army surplus ammo box
a hollow tree trunk along a walking trail; it's filled with
plastic insects and an essay about nature's marvels. We find a film
canister dangling from string inside a fencepost on a landscaped traffic
triangle containing a tiny logbook crammed with signatures scribbled by
those who preceded us.
Geocaching is addictive. Besides
exploring close by, when my family travels far by car, we pinpoint
caches along the way and stretch our legs finding them.
people walking around with GPS units and now know what they're up to. In
a very geeky way I enjoy finding caches, reading logs, leaving notes,
and slinking away, unnoticed except perhaps by other cachers. As I've
learned, they're everywhere.
• Learning a new skill such as geocaching gets you moving and helps you stay motivated to be physically fit.
• Exploring on foot in the fresh air can give you an extra boost of energy.
