I would like to contribute information from Missouri District #10. While I haven't ridden it, there is a map of it on the site. I know its not a GPS file,. but it's a start. I'll keep looking for more.
Do you want us to research the route....enter it into.... lets say TOPO7....ride the route then send you the file?
