>>1340361Hey sorry didn't see your post sooner. Been a while since I walked past this spot in Bay View but I assume they still dock there on occasion (top pic is where the Challenger/Conquest go). Think that's a cement silo they load/unload at. If you drive on the Hoan bridge over Jones' Island you can see larger docking points.
There's some accessible roads in the Jones' Island area where you can bike around, some tugboats moored there too. If you head down there check out Kaszube's Park, smallest one in Milwaukee.
