I highly recommend the movie, though what I got out of it was something different than the person sitting next to me. If you watch this movie ($1 at Redbox), tell me and other readers what you thought of it.
I then went looking for maps of the PTC and came across this one accompanied by a video of a hiker and video journalist, who chronicled his own transformation along the trail in selfies taken every mile of the 2,660-mile trek. While watching the man morph into a tougher and wiser version of himself, the background of the California/Mexico desert, the high Sierras and the Pacific Northwest Cascades takes the viewer on a wild ride through a vast, rugged wilderness.
The video journey takes about 4 minutes. Have fun - without the effort - or the reward. The map at the bottom of the webpage is interesting also.
