As someone who grew up in the Northeast, I feel like there aren't very many walkable towns unless you're essentially in the Boston or NYC suburbs. So many towns in upstate NY, MA, and PA had their main streets turned into major thoroughfares for cars... which made them completely unwalkable and miserable to live near, eventually killing the town. Most of my relatives who live near "cute" downtown strips can't even walk to them because their towns haven't bothered to build sidewalks even in the moderately dense parts of town.
