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 back in early March of 2012.
It may have been the winter season here in Chicago, but shipping traffic on the Calumet River is year round. The huge Great Lakes and ocean traveling freighter ships, require multiple tug boats to safely navigate them through the Calumet River Channel on the far southeast side of Chicago near neighborhong Hammond Indiana.
