|The corner of the Duluth harbor by Bayfront Park was a busy place on Saturday. The Marine Tech dredge has been there for a couple weeks (and will be there until the ice comes back). The Greenwing came under the Lift Bridge at 2:30 and went to the AGP elevator to load grain (background). An hour and twenty minutes later, a sister ship, the Bluewing, arrived and moved into the berth at Cargill, just next door to AGP. Both ships are 611 feet long, were built in China in 2002 and were named after ducks. Photo taken on September 22, 2007.
