Amazing how much control Chicago has over the great lakes when they have the smallest stake of anyone.
They can use the term "Shipping canal" all they want but the fact remains that its value as a trade route is minimal at best. The reality is that it was created to prevent Chicago's own sewage from washing up on their shoreline.
Its greatest value is probably in moving pleasure boats back and forth but that could be dealt with by the free market. (boat elevator)
Yup, this is a good idea. Seal the Chicago Sanitary Canal to save the Great Lakes from carp and return the crap to Chicago where it belongs.
Simply a brilliant plan I tell you. A for sure shovel ready project to start ASAP!!!!
