From the Chicago Tribune:
“For years Sararose Krenger and her family joked that alligators lived near their Ravenswood Gardens' home which is along the Chicago River.
“Today, Krenger, 22, and her family were on their boat traveling on the river when their joke became a reality. They spotted a three-to-five-foot alligator basking in the sun along the bank of the North Branch of the Chicago River just north of Belmont Avenue.
“It's the second time in less than a month that an alligator has been spotted in the same area, officials said. [earlier one was caught; this one escaped]
“"My father said there's an alligator and we said 'pretty funny', but there really was an alligator there," she said. "We thought it was pretty cool."”
