Usually, you'll find those Mass-folks are from the "North Shore" and North/NW of Boston towns.. (Somerville, Malden, Melrose, Stoneham, Lynn, Revere, Saugus, etc). The Shore Shore folks mostly migrate 'down the Cape' or more south .. to Marshfield, (AKA "MarshVegas") Scituate, Hingham, etc.. You'd think the trip across Boston Harbor was a million miles wide... some folks from either shore have never been to the other...
