I've written Hike Your Own Hike: 7 Life Lessons from Backpacking Across America. I've walked across America four times and visited over 80 countries. I'm the first guy to yo-yo the Continental Divide Trail. I also thru-hiked the Pacific Crest Trail and Appalachian Trail southbound. I just returned to the USA after traveling in Eastern Europe for three years and finishing my second book, The Hidden Europe: What Eastern Europeans Can Teach Us.
