This 840 mile ride can be ridden over several days. It is intended for a street bike or medium or larger dual sport. It can also be ridden in day or weekend segments. The ride covers history and points of interest through the Kettle Moraine of SE WI, the Door Peninsula, the Fox valley, and back down to SE WI. A ride report with photos and more details about points of interest can be found here: http://www.advrider.com/forums/showthread.php?t=723879 A GPX can be downloaded here.
My wife and I have a summer home in Sister Bay, Door County, Wisconsin. Last year the Harley Owners Group had a state rally in Two Rivers, WI. just six miles north of Manitowoc. We had the opportunity to go through the Manitowoc Crane Company on our tour. That big red crane in the lower right corner of your photo. The guy who led our tour said that thing sells for $35million. Yes, I said $35million! Oh, I know all those roads and ride them all the time. Good report.
I can post GPX to ADV again so here is a file. Downloaded 170 times from here: http://dco43054.com/phpbb/viewtopic.php?f=2&t=32
