i realize this topic has been a bit dry since last summer...
But I was just playing around geocachers.com and looking at some info about a particular travel bug. On the right side is a link to view in google earth. I clicked it and voila, all the stops on that particular bug were pinned. (I did uncheck every other box to get a prettier view.)
I was able to right click the route in the left window and save it. It gave me 2 options, kmz or kml. I haven't had any luck finding a way to import it into any of my map stuff, but I have more coming next week and I'll try that.
