Donate today to AIDS Network's longest ongoing event, the Red Ribbon Affair! Entering its 20th year, the Red Ribbon Affair is a black tie gala event at Monona Terrace highlighted by one of the area's premier silent auctions. This year's event will be held on Friday, April 16th. Last year, over 100 local businesses donated $30,000 worth of items to the silent auction, helping fund much needed care and preventive services.
