Have you been here? The Jurica-Suchy Nature Museum at Benedictine University in Lisle? We just went there for a field trip with Oscar's class and what a fun place! If you like dead stuffed stuff, which we do. It's super tiny but it is crammed full of treasures. I often think these small scale places are much better with little kids. Less exhausting for Mom at least. It's like a squished up, concentrated version of a trip to the Field Museum.
