Came across this one when I was looking for photos to post.  Reminded me of one of the advantages, I suppose, of digital photography: When Jon goes out for a hike, he often photographs the map at the trailhead.  And then consults it via the image-viewer on his camera.  I prefer paper myself.  But then again, often the trailhead maps cannot be had, so if you want your own, copying it yourself is the only choice.
