I hope you're right - I think typically mid-October in that area is near the tail end of the foliage season, so if the cards fall just right, you might still catch some amazing color. If they don't, you might end up with more yellows/browns, which still won't be awful looking but not quite the full array of colors that are possible.
The good news is, coming up from BOS you should drive through somewhere where it is still peak color, my guess is that you're more likely to see it in coastal NH or far southern Maine.
