I am new to Chicago and the state of IL and was looking to take my girlfriend on a small 2 day roadtrip over the Valentines weekend somewhere outside of Chicago. Some of her friends suggested Madison. Is that a good 2-3 day retreat or are there other hidden gems in IL worth exploring?
Ideally I was looking for something with a short 2-4h max drive from Chicago.
Also, looking for a reasonably priced weekend (nothing overly expensive).
