The day I can spend an hour fighting Google Maps to get a route that covers all lower 48 states is the day I’m finally a Google Maps convert. Typing in city name is for wimps. Dragging that blue line all over the country, now that is GIS baby!
Sure it isn’t efficient, but the Google servers are slow and I gotta get back to work. Now all they need is save to KML.
Frank has the info on how to create KML (append &output=kml to the end of the permalink), but my 48 state route doesn’t seem to work.
