Tug boat pulling a huge Canadian great lakes freighter ship. Chicago Illinois USA. Sunday, March 4th, 2012., a photo by Eddie from Chicago on Flickr.
I took this photograph on a very overcast, cold and windy late winter afternoon, back in early March of this year.
A powerful river tug boat, helps guide and stabilize a huge Canadian great lakes freighter ship through the Calumet River channel, just south of the East 100th Street drawbridge, in Chicago's own South Chicago neighborhood.
