I once met a man who was just trekking across the country. Took a rest next to me at the bus stop in my city with his a big ol’ frame backpack; one of those ones you would take on a long multi-day backcountry hike with a sleeping bag. He said he had just come down out of the mountains. Until then, I had not met a single person who even tried to make that journey in either direction on foot, but this person apparently would walk huge portions of an entire state on a frequent basis. You could tell he wasn’t like other homeless people. He actually seemed happy.
