Ken Ilgunas (born June 22, 1983) has hitchhiked over 10,000 miles, traveled across Ontario, Canada in a birch bark canoe in the style of the 18th Century voyageurs, worked as a backcountry ranger in the Gates of the Arctic National Park, and hiked the controversial 1,700-mile Keystone XL pipeline. His memoir, Walden on Wheels, is about his two-and-a-half-year radical living experiment in which he secretly lived in his van at Duke University, where he received a graduate degree in liberal studies. He was raised in Wheatfield, N.Y., and currently lives on a farm in Stokes County, N.C. His website is kenilgunas.com.
