My husband will be undergoing a 9 week medical treatment in the Naperville area this summer. We will be staying in Naperville, but our plan is to go some place "fun or interesting" at least one day each week, on a weekday. He should feel fine so our activities will not be restricted in any significant way. We are looking forward to the chance to really explore the area at a relaxed pace, but the options are overwhelming and are wondering about the "hidden gems" that might not be at the top of typical lists. Also, would love your suggestions on transit to and from Naperville i.e. car vs public transportation.
