I second Mark's thanks.
I generally plot out the draft route for my RDs using Google Earth or GMaps (milermeter), take a screenshot of the route, then drop the screen shot into Corel Draw. Then, I trace the route with colored dotted arrow lines (sample attached). I save the image as a PDF and email it. This seems to do the job.
Of course, not everyone has CorelDraw or Adobe Illustrator (comparable programs). I have found Open Office Draw less friendly to create this kind of image. Where PlotARoute will really come in handy is when I am proposing a multiple-loop course, or one in which the same path is traversed more than once. A great tool to have. Thanks, Jeff!
