While doing some looking around on the web, I found that someone with the online name of "rvbooth" had mapped Blue Highways in 2005 on Google Earth. It's a very nice job of mapping his route and includes polylines between the stopover points.
The difference between that earlier map and mine? The earlier map shows only the stopovers that William Least Heat-Moon (LHM) made, whereas I am trying to map every point along his route that he mentions in the book, whether he stopped there or not. Second, my map includes the relevant quotes from the book whereas the previous map does not. Third, in keeping with my blog's stated purpose, I am including entries which are my own impressions, thoughts and recollections as I read LHM's words. In a sense, it is like I am traveling with LHM, but keeping my own journal as I go. In that way, I go a little more in depth into the book than the earlier map does.
I think it's a great resource - and will give you some idea of where we're going. To see the map, you must have Google Earth or the Google Earth plug-in on your browser that will allow you to see Google Maps in Google Earth view.

To compare with mine, go here to download my Google Earth kml file (in progress).
Happy traveling!
