OK I have a slightly new route for the River run that I am posting. The difficulty level of the Fife lake run is very high according to some who rode it this weekend so I think we will try the Manistee River Run on Sat. See the gps forum. I have also added some warning points for the Fri PM ride in waypoint form. You may want to download them as well.
Thanks to Jack and Carter for pre-running the routes and providing some good info.
