There is a fellow named Marshall Massey walking from Omaha, Nebraska to Harrisonburg, Virgina: a distance of 1150 miles. He started on Saturday, May 13 and expects to finish July 31. He is currently about half way across Iowa.
He is writing about his journey in his blog at http://journal.earthwitness.org/. Be sure to go to the archives and read the entries in order from the oldest to the most recent.
This may not be everyone’s cup of tea. Marshall is a Quaker, an environmentalist and a peace activist. If you are not familiar with Quakers you may find his description of his decision to walk to Virginia as a “leading” from God certified as such by his Meeting as somewhat strange. As a student of Quakerism I find a modern American writing and thinking in a manner similar to the great Quakers writers of previous generations fascinating and wonderful.
