My husband and I are taking a four day road trip in mid-October (flying in and out of Hartford CT) to the the New England vicinity. We've never visited the Northeast and need some advice on how to put together an economical road trip. We'd really like to spend one day in Boston and then spend the rest exploring New Hampshire and Vermont, maybe setting foot briefly on the southern coast of Maine.
Any advice, ideas, off-the-beaten-path hiking or driving, etc. would be greatly appreciated.
