Hey I'm trying to hack the Oregon Timber Trail route (just the route, not the support). I've started a Google Earth document, and shared it on my google drive.
https://drive.google.com/file/d/0BzSkRXTEeCqVa3Uza1pZdzc0SjA/view?usp=sharingDownload, then open in Google Earth. Feel free to browse and comment. I'd love to hear from others who think they know where it goes....
