Hi Sharon, In terms of Northeastern historical sites, you can't get much better than Massachusetts, in particular Boston and its Revolutionary War history. Don't forget the Plymouth area, too, for all that pilgrim heritage! From Boston, you'll probably want to head north into the Maine and New Hampshire woods for your best shot at early fall colors (late September will still be quite early to get the full foliage show, I think). Here's a link to Away.com's fall-foliage guide for activities and average timings in different states for peak fall colors: http://bit.ly/fqdgVv
