I made a few improvements to eastern Massachusetts and Rhode Island for you. They're far from perfect (if you use it,
please take out that Nantucket, it's wildly inaccurate), but I tried to fix a few of the more noticeable inaccuracies the great Massachusetts had. The entire eastern coast has been redone or edited (Boston and Essex were drawn from scratch), and I changed the borders for Barnstable, Bristol, Plymouth, Norfolk, Suffolk, Essex, and consequently Middlesex counties. I made a few changes to Rhode Island as well; I adjusted the northern border, got rid of Patience Island (too small to relevantly appear on the map), expanded Prudence Island, edited the southern coast, and improved Block Island (great vacation spot). I hope you enjoy this, and if there's anything else you would like me to change I can do so if I have time.
