The Peggy Notebaert Nature Museum — including the Judy Istock Butterfly Haven — goes adults-only for this evening event allowing visitors a unique chance to stroll around the museum with no kids in sight and a cash bar serving local beer and wine. Featured breweries include Finch's, Revolution, 5Rabbit, Metropolitan Brewing and Two Brothers. The night also includes a nature trivia competition. The winning trivia team even will be awarded the coveted Golden Cockroach trophy.
