Armchair traveling

I am traveling again my by armhair. This time it is by books-on-tape “River-Horse” by William Least Heat-Moon, Across America By Boat. He had written “Blue Highways”, one of my favorite books. It is of his journey across the United States by river, that is, all except for 75 miles. I am in for a treat. To make it doubly interesting I am following that trip in great detail with google maps.
