Another change?

After a pretty terrible tutorial last week i think i have a new lead .

http://www.geocaching.com/

Has anyone done this before? It sounds great.
- you get map coordinates from the website of where someone has hidden a wee box
- find the place
- find the box
- write in a wee book that you found it
- then it has something in it the you can either take and replace with something else of just leave it.

!!!! Excited YES!!!
