Civil War historian Dr. Wayne Wolf "interviews" President Abraham Lincoln (actor Michael Krebs) for his take on the 150th anniversary of the Emancipation Proclamation. There will be an opportunity for the audience to ask questions about Lincoln's pivotal decision.

Interactive learning centers include a barn slide, apple orchard and chicken coop. Maggie, a life-sized fiberglass milking cow sponsored by Golden Oaks Farm in Wauconda, will be the focus of the new exhibit. Maggie is over five feet tall and features a working udder that recirculates the water that children "milk."
