My son recently had a frightening experience as he and his fiance were enjoying a leisurely walk along the lakefront on one of the beautiful fall days we’ve been having lately in Chicago. They noticed something on the ground and Laura wondered aloud what it was. Mike said it looked, at first, like a piece of garbage, but as they got closer, it appeared to be a dead bird. Just as they were passing it, the thing opened its mouth, exposing fangs, and hissed loudly for several seconds and then spread its wide wings. It was a bat. In order to understand Mike’s terror at that moment, I need to take you back many years to a warm summer day when I thought it would be fun to take my four young children for a walk along the Fox River.
