JHK chats with tugboat fleet owner Rob Goldman about the revival and future of shipping on America's inland waterways. Rob's company, NYS Marine Highway runs tugboats that push cargo barges through the Erie Canal system and the Great Lakes, as well as along the Atlantic Coast. Rob graduated from Rensslaer Polytechnic as an Architect, got into the pleasure boat marina business, and eventually started his shipping company. It's not your great-great-grandfather's Erie Canal anymore.
