Today on "The Metro," we're wishing the Belle Isle Aquarium a happy 120th anniversary! Belle Isle Conservancy CEO Dr. Megan Elliot joins the show to tell us about the celebration happening at the aquarium on Sunday, Aug. 18. You'll also hear a conversation from the back of Accessibili-D with Detroits Chief of Mobility Innovation Tim Slusser. It's a new autonomous vehicle shuttle providing a service and testing new technology.
