Try Beverly. It’s Illinois’ oldest active cache, one of the oldest period, and it’s a sweet walk in one of their big forest preserves. There’s another cache along the way, making it a two-fer. Should take less than an hour round-trip. I’d have to look for details, but it’s right around the Schaumburg area, so should fit right into your route. The Chicagoland area is actually pretty blessed with good quality caching in the tree parks. Just watch out for the tree cops and the back-in boys 😉 .
