Do you not know how to read a map? On the Wisconsin side of the river and hewing close to the river, there are 7 dots between the Helmart in St Paul and Trempelau which is most of that 188 mile trip. There are more stores near La Crosse but generally, that would mean about 26 miles between them. However, those aren’t “grocery stores”. They are convenience stores. Yes they have edible food but they aren’t someplace you could buy food to prepare a meal in camp. I visited many of them as I made my way down the river.

I will say that on that leg of my trip, I didn’t camp because that leg was during the Labor Day holiday and campgrounds were full. I stayed in hotels and ate in restaurants over the 3 days it took me to transit that section. However, even that was not as easy a task as one might think. There were slim pickins’ all along that section for ever restaurants.
