Another ride with points of interest that some may want to ride is the Yellowstone Trail in Wisconsin. It is about 435 miles of mostly backroads with around 90 points of interest waypointed along the way. Pictures and information can be found here: The Yellowstone Trail - Forging Transcontinental Routes The GPX file can be downloaded here: http://dco43054.com/phpbb/viewtopic.php?f=2&t=14
