In the Ratchet death scenes there is a lake freighter named the "Sarah Spencer". I thought I'd seen this freighter before, sure enough on the drive home, I realized it is currently docked on the Maumee River in Toledo, OH. Today as we passed it, I had my daughter snap a picture.
Yeah that would be it. That scene with Ratchets death was shot in Ecorse Michigain at the "Nicholson Terminal & Dock Company". The two Boblo Boats "St. Clair" and "Columbia" are still docked there and were sitting across from the "Sarah Spencer".
