I’d give State College some real consideration. I grew up there and went to Penn State for my undergrad and it’s quite a bit different now, but despite it being a college town, unless you live close to downtown, you can pretty much avoid most of that. A lot of my friends who still live there are in Boalsburg which is outside of town and has a different, more local feel. My grandparents lived in the DC area and that was about a four hour trip back when the speed limit was 55 and there were a lot of two lane roads on the way. I think it actually hits a lot of your requirements.
