I love the idea of the latest spinoff of geocaching - Skiocaching. The sport is trademarked and promoted by Mountain Dynamics Inc. and is described as this:

Skiocaching is a GPS-based treasure hunt held at a ski resort. Now you can ski/snow board while also testing your wits and navigation skills!

Skiing already tests my wits and navigation skills, but if you'd like to see the calendar of upcoming events and sign up for the Skiocaching newsletter, visit Mountain Dynamics' Web site.
