My boyfriend and I are headed on a road trip from NJ to Chicago for Lollapalooza in about a week and are looking for good places to visit on our way back. We already booked a hotel to check out Cedar Point in Ohio on our way there. I should also mention we'll be getting a late start leaving Chicago to head toward home, probably around 5 pm so we don't want to drive more than 6 or 7 hours that night. We're not opposed to detours and are lucky enough to have plenty of time to travel and explore but relatively limited funds. Looking forward to your suggestions!
