Heard this through hiker last night at the Westfield Athenaeum. His real name is Sam Ducharme and he has a YouTube page showcasing his Appalachian Trail hike. I haven't checked out his videos, but his presentation was great and an inspiration to all those who have experienced or desire the life changing expedition.
I picked up his book and look forward to the read.
Thanks, Sam I am,
your new friend, the Happy Hiker (both ends to the middle 1974-75).
