I didn't mean Central MA proper as in Worcester County because none of the towns fit OP's criteria. They're all quiet bedroom communities, zero walkability, and nothing to do or see unless you consider going to Target and Buffalo Wild Wings a great time. I meant it more like geographically in general. Western MA is huge in its own right by that same token. Stockbridge and Amherst / Northamption are not exactly neighbors.

OP also mentioned somewhere safe enough you could walk around at night. Main South is not that. I watched two teenagers jump out of the car right in front me and start shooting at another group of teenagers standing outside the 7-Eleven in broad daylight in August. I gave my statement to WPD and the cop seemed visibly annoyed that he had to be outside while it was so hot. Lol. Main South.
