The bigger question… are the berkshires part of what is culturally considered western MA? My take is
No! I grew up in Ludlow and our TV and Newspapers never mentioned the berkshires. Come to find out they get their news from Albany! Let New York take them.
The other question is those poor towns in western Worcester county (warren, new Braintree, oak ham, hardwick) they seem to be in no mans land.
One of the things I took for granted living there was (aside from party pizzas) was that the TV news was very local. In eastern ma it’s a huge expanse of towns and in VT you have to hear about western NY half the time!
