Family Reunion on a large scale

I have decided to go to my family reunion. It's held every three years. This year it will be held in Lyndonville, VT. I have never been to New England and I have been told that a driving trip in Vermont and New Hampshire is something to behold. I looked up Google maps. It is almost 1600 miles from KC to Lyndonville. I think I'll drive and perhaps plan a stop at Niagara Falls, NY.
