    "It went from a farmer's / blue collar town in the 80s to a wannabe Concord / yuppie town. sonce there are so many garden-style apartments it will always be a mix of upper middle-class and regular-income people. Excellent schools and well maintained, but the yuppies can be an annoying presence."

  • Jack B.
    "Conveniently located between 128 and 495, with super-easy public transportation that brings you right to both Cambridge and Boston, Acton is ideal for couples and families. It's an upscale community with recreational opportunities galore, as well as fine restaurants and shopping at not one but three shopping malls within a 25-minute drive. Money Magazine rated Acton #16 among the best small towns nationally. Housing prices are only a little more than the median for the metro Boston area, but considering the ample space, easy commute, and low crime, Acton is still a bargain by Massachusetts standards."
