This is a cool website for GPS addicts.  It allows you to upload a GPS track and then "fly" the track via google earth.  It is very interesting to see the track played back and be able to see the ups/downs, etc.  I've got some tools that will play back GPS tracks, but not with the 3d effect that this has. http://www.gpsfly.org Here is a "fly" of a BOTW hike that someone posted.  Looks like it goes up Bagby and makes a big loop through the heart of the wilderness: http://gpsfly.org/g/252
