Congratulations! You've found it! Intentionally or not! What is this hidden container sitting here for? What the heck is this thing doing here with all these things in it?

Standing on a hillside in Lake George, N.Y., I pored over the letter left in a Tupperware container that I'd found just moments before on a rock shelf. The note explained the somewhat mischievous rules of a new high-tech sport called geocaching (pronounced "geocashing"). Flush with excitement, I read on: This container is part of a worldwide game dedicated to GPS (Global Positioning System) users. The game basically involves a GPS user hiding "treasure" (this container and its contents) and publishing the exact coordinates so other GPS users can come on a "treasure hunt" to find it. Geocaching is a relatively new phenomenon. Therefore, the rules are very simple: 1. Take something from the cache. 2. Leave something in the cache. 3. Write about it in the logbook.
