Cool! Do you know what interstate you'll be taking through Ohio? If you're going by way of Columbus (I-70) - I live 20 minutes north of it near Dayton (I-70 & I-75 intersect there). If I'm not working by then, there are lots of restaurants right there. We could meet, no problem.
Unfortunately, I couldn't put you up for the evening. I live in a refurbished hospital, rent a small room.
If you're taking a northern route (like I-90), that would be too far for me to drive.
Anyways, let me know! (by PM if you like)

P.S. I just checked Google maps. I-90 looks like the way you would go. It's almost a straight shot from NH to NE.
