Okay, I'm a newest of the newbies here, but I'm already using Google Earth with the Geocaching Network KML loaded, so caches show up. Way cool. If I'm planning a route from Eugene to Portland, for example, I can find all the caches along my route, and pick the ones I want by how close they are to the path I'm taking.
My husband is Dutch, and I'm already planning--with the help of Google Earth-- what caches to find in Holland that are fairly close to his mom's house.
