Gary Sizer is a former US Marine who hiked the AT in 2014. We never met on the trail, but we are now Facebook friends. Gary wrote a book about his experiences and while that is going really well, his current claim to fame is an amazing picture posted on Reddit that shows the devastating effects that the AT can have on a hiker's body. Gary is a good sport for allowing this to be shown here, though, as it has been seen more than 3,000,000 times, it might be regarded as a trifle late to keep it under wraps!! There are a bunch of ways to contact Gary and share his story. His books (Kindle, paperback and audiobook) can be found on Amazon. He's accessible on Twitter and Facebook, as well as at his website, wheresthenextshelter If you'd like to follow me, I'm also on Twitter and Facebook and you can find all the podcasts, plus videos and photographs, at my website mightyblueontheat
