I just pulled the data out of my Garmin GPSmap 60CSx from my dog sledding trip. I just love being able to go into the wilderness and just drop my GPS somewhere with a little visibility and get a perfect track log. I fired up GPS Babel and got the data into KML format and you can now see it in Google Earth, check out Wintergreen 2009 Photography Workshop in Google Earth.
If you don’t have Google Earth installed, you can see it in Google Maps using your browser too.
