Me and my friends (all guys) are planning a road trip from NJ to Chicago. Googling about the routes and other details, we found that highway 80 is the best choice and Cleaveland being the best stopover. We are planning for 4 days road trip, so please guide us with best possible routes, stopover and things to see/experience on the way to Chicago. We are ok to try new routes, and are looking for fun and enjoyable road trip. Also, anything exciting in Columbus/Indianapolis/Cleaveland..?
