Plenty of places in the Northeast are potentially great for this. I live in a suburb of Philly, there's a train station into Philly a mile away, a major shopping center also about a mile away, a downtown area with lots of shops and restaurants, and two neighboring towns with similar downtowns. The schools are within easy walking or biking distance. The infrastructure is pretty hostile but the distances are perfectly reasonable for cycling.
