I used to drive from Chicago to Cleveland quite regularly. You can safely drive about 76 - 77 mph on the Ohio Turnpike. Anything over that is risking a ticket, and they do have air patrols as well as cars. As far as cool things to check out, South Bend might be cool if you're a college football fan, Toledo has the newly completed I-280 bridge over the Maumee which has a single pier with glass walls anchoring the suspension cables across, and closer to Cleveland, the Cuyahoga Valley is very cool for scenic driving down toward Canton. Hope you have decent weather!
