So I'm guessing you are going to take Rt. 84 from CT across NY and into PA, come down Rt. 81 through Scranton-Wilkes-Barre, and then pick up I-80 all the way through PA into Ohio, picking up Rt. 71 down to Cincinnati. I'm very familiar with the part of the trip that would incorporate Danbury, CT to northeastern Ohio. I don't think there is anything interesting enough to make it worth stopping in the middle of the trip to see it. I've always wanted to spend some time in the Pennsylvania Wilds, but when traveling cross-country and not really on a vacation, there's never been time to do that, and I have not really had the right gear with me anyway. I think your best bet is just to drive straight through and get to Cincinnati. I'd suggest packing your own good sandwiches or whatever in a cooler, and take your own good coffee in a thermos if you are a coffee drinker. Once the thermos coffee runs out, you'll have to purchase more, of course. The rest stops along 84, 81, and 80 in Pennsylvania are handy, but only have vending machines with hot and cold drinks and snacks. I've never had much luck eating at truck stop restaurants (service seems very slow if you're not a trucker), but have learned to get hot or cold drinks and sandwiches/snacks at those little travel stores where you stop to get gas. And of course, McDonald's. Be careful of the 55 mph. speed limits through Scranton-Wilkes-Barre. The locals ignore it, but with out of state plates, I'm afraid to speed through there. There is a lot of road construction going on all through Pennsylvania right now. It won't make you come to a stop, but there is a lot of slowing to 45 or 55 and one-lane closures all across PA, particularly in eastern PA near the NY line and then again in western PA when you're nearing Ohio. I just drove from Beacon, NY to Youngstown, Ohio on Oct. 31, so my info is current.
