That's really interesting. I'm assuming all the clips were from earliest to latest since Katahdin was shown last. The music reminded me of an older (70's or 80's PBS special). It's cool to see how the trail terrain changes from south to north.
Cool idea in theory, but I didn't like the actual result. Not a big fan of the music and the headache/nausea-inducing fast video. For those with a weak stomach, try this: right after you hit "play", hit "pause", then slowly walk the cursor across the time line, and treat it like a photo slideshow. 2:26 reminded me of Franconia Brook Trail coming back from 13 Falls, where you can see straight a long way and see the hole at the end of the tunnel.
I'd love to see the raw video. Good job by him for the hike and taking all that video.
