We're big fans of anything that involves ice cream, so this combo of history and make-your-own sundaes is right up our alley. The hands-on family activities, games, demos and tours are just the cherry on top. Free with admission. 1-4 p.m. (ice cream 2-3:30 p.m.) Sundays. Naper Settlement, 523 S. Webster St., Naperville.
