Well that's pretty cool. Score one for Old School!

After my most recent trip I'm considering a basic GPS so I can overlay waypoints on maps to improve the accuracy of the displayed trail. My last map was good enough for the trip but my inner engineer was annoyed that there were switchbacks and other trivial features not accurately reflected. I'm also the type who is likely to enjoy geotagging photos for Google Earth, just to annoy my indoorsy-type friends.
