I say “wonders” because I’m no expert on the best ways to fight this crazily contagious coronavirus. Few of us are. I’m glad to have a mayor who listens to the experts, and Mayor Lori Lightfoot did the right thing at the end of March when she closed Chicago’s lakefront and The 606 trail. Her move sent the message that this virus is serious, that congregating can be deadly, that we need to stay home.
