My husband and I are beginning planning a circular trip in the fall from central Maine to Niagara Falls, up to Toronto then on to Quebec and from there returning home. We can go thru VT and stop over in Quechee on the way to the Falls or via I 90 thru Mass and NY State. We prefer 6 to 7 hr legs of the drive. What are interesting spots to be included between VT or Mass and Niagara Falls. It would be great to do this enjoyably but frugally. What other suggestions are there in this circle to make this a great trip. We would probably look at 7 days start to finish.
