No Blue River
“We are thrilled for the Cubs and for all the people who live here and share in the joy of this wonderful winning team,” said Margaret Frisbie, executive director of Friends of the Chicago River. “However, we hope this is a rumor of idle fun and speculation rather than an actual plan. The Chicago River downtown and elsewhere is alive with fish and other life including beavers, muskrats, and birds, like the state endangered black crowned night heron that I saw on the riverbank at LaSalle Street less than two weeks ago,” Frisbie continued. “I know that the mayor is a real river champion and I am sure he will do what is right for the river.”
