A friend of mine turned me on to this site
http://www.spotwalla.com/You can set up the dates of hike (or other tracked activity) and it will grab the information from your shared page and automatically create and update a permanent page. And it will do this for multiple activities.
And of course the SPOT data can be exported as a .kml file so that the route can be saved on google earth.
But, I Imagine that if I start taking the backcountry stuff more seriously, I will have to go out and get myself a real GPS.
