In Oswego, a massive, rust-covered container ship glided across Lake Ontario Wednesday morning. It eased toward the Port of Oswego and abruptly came to rest after bumping against the dock.

The 24-foot-tall ship was carrying equipment from Germany that will head to a brewery in Rochester. The port is expecting another shipment of similar equipment next year for a brewery in Fulton.
