We are taking a road trip from Chicago to Niagara Falls in a few weeks. We are planning for about a week round trip, spending 2-3 days of it in Niagara Falls. The rest of the time I would like to spend stoping at sights, etc along the way. I was wondering if anyone has made this trip and knows of anything I should not miss along the way or just knows of sights/attractions that are worth a little bit of a diversion. I am thinking about taking I80 to I90 route, but if something is worth it, I am willing to change that road plan. Just looking to get the most out of our trip.
