I haven't been to the northeast so I have no idea of the best roads to take across New York, Vermont, and New Hampshire. We like to avoid the supper slabs as much as possible. How is US 20 from Buffalo to Utica? How about 12 and 28 to the Adirondacks? What is the best way from Adirondacks to Lake Champlain? Lake Champlain to Shelbrune, NH?
