The northwest branch of the Chicago River was my watercourse as a boy ("Pilgrim at Shit Creek," HCN, 7/22/13). It was also polluted, but it was all we had. We rafted it, wading mostly. Since then I've gone back in a canoe and found all manner of wildlife -- from foxes, deer and coyotes to songbirds, ducks, geese, muskrats, beaver, and turtles -- even on the banks downtown among the skyscrapers. Seek and ye shall find. The biosphere is the fabric of our lives.
