The Mississippi basin and Great Lakes are equally wonderful waterways, but I too would like to see them separated. Or turn Chicago back into a swamp instead of a flowing river. After all, the original name was chicagoua which was the word for the wild leeks which grew in the swampy ground there. The Chicago river barely flowed at all. How about turning the whole thing back into a wetland?
Doubtful, but this is hopeful.
