The Ins and Outs of Oak Trees

Celebrate OAKtober with a walk through an oak savanna, and then relax in Mayslake Hall’s historic library with some white oak bark tea. Take a docent-led tour of the library and study, both featuring 100-year-old oak walls and flooring, and leave with acorn flour recipes from the 1920s. Ages 18 and up. $10 per person.
