I went to school out there and have friends from the surrounding areas, it's nice if you're wanting something more rural but still near things. The key to it is a lot of the towns were built 100-200 or so years ago, when it actually was necessary to build close to each other in community.
Aye, but I bet GP's home town in Spain is much more pleasant to walk in from November to March ;-)
That aside, there are some real gems among Western Mass towns! I wonder, with all the empty land in this country (even in places very hospitable to human life), if it's possible to found new towns built in the "European" model of a central plaza surrounded by multifamily, mixed-use developments within walking distance? Were I a billionaire, this is the sort of stuff I would explore.
It's not geography, it's history. The only nice places in the US are places that were built before cars.
I also live in a small town of around 2000 in rural Massachusetts. Within the same walking distance I have: full elementary school (kindergarten through 6th grade), public tennis and basketball courts, a public indoor gym, a grocery store, several restaurants, several bookstores, several banks, a pharmacy, a bowling alley and a few more misc stores. We also have public transport to the nearest big town but it is only a few times a day.
The only reason my town is dense and walkable is due to geography. It was settled 250 years ago and it is nestled on a river between two "mountains" (really just big hills) so once all the available space filled up 100 years ago it just stopped growing (my house is on the outskirts of town and was built 115 years ago).
In comparison I grew up in a sprawling small town in the US midwest which has embraced even more sprawl since I moved 30+ years ago and I hate going back. Its just souless and unwalkable as it has endless land to expand into and no plan to keep it human scale.
