Thru-hikers in America have some nice options for summer-long walks where they don't have to bushwhack or stress about navigating. The Appalachian and Pacific Crest trails allow that type of passage. Alaska also has a gravel pathway across the state that Ned Rozell and his dog have hiked twice, one time 20 years after the first.

As far as he knows, he is the only one to have covered that ground on foot.
