An east coast friend introduced me to this website: http://route6walk.com. It's about a retired newspaper man, Joe Hurley, who walked US Route 6, a highway that stretches all the way from Cape Cod in Massachusetts, to Long Beach, California. (Who knew there was a single route across the entire U.S., and a walkable one at that.) Mr. Hurley traveled from east to west, and had a photographer with him. I am copying a couple of the photos below. We have exchanged a few e-mails and Mr. Hurley has been generous with his offer of advice/contacts and so forth.
(Mr. Hurley has a book for sale through is website. Photos are by Travis Lindhorst.)
