The idea is simple: take some item and hide it somewhere in the world, record the latitude and longitude using your GPS receiver, post the location to the Web so that others can find your stash. Most people leave a five gallon plastic bucket with a few items inside and a logbook. When someone finds the bucket they take an item, leave an item, and sign the logbook. Take a look at the original (read "non-pretty") page."
