Manitowoc - A) Leist Road to Cnty.Rd.S (PnP or 4.5 miles) (WI)
Flatwater float, but gradient will be grungy (likely portage).
The sportsmen's club (river-left) has been very accommodating (when I've found anyone there) to allow river access for park-and-play or for the run. If they are present, stop in and say hi ... maybe even have a cold one after your run.
Parking is fairly informal, just don't block the road. Carry back up the driveway to where the river is nearest to put in right at the first waves.
If you walk anywhere into the woods, be mindful of poison ivy which is pervasive here!
I would also repeat the notice that you are in the heart of dairy country. A farm with a large herd lies just upslope the right/south banks. As a result, air and water here tend to reek with the odor of manure. This diminishes enjoyment of 'full out' play here, as rolling, swimming, or getting too many face splashes seems a very bad idea.
