Mark Twain called the basin of the Mississippi River, “The Body of the Nation.” It gathers slowly in the upper midwest. It is fed from a remarkable number of rivers and a remarkable number of states. It winds its way though the center, through the very soul of our country. There are countless stories and mythologies and poems written in homage to this beautiful languid body of water. There are lives who live and breathe because the river flows. There are whole ecosystems depending on the great artery to bring them life.
