The leaves this year have been simply stunning with a wide range and depth of hue from dark brown to bright glowing yellow. Often on the same tree, especially Birch. Somehow I don't have any good photos and have now missed the best. So I'll let you Google for some.
Each time I have been to Boston it's been the Columbus weekend which Willie Walker says it a bit too early for the famous New England 'leaf peep' spectacle. Perhaps 'one year'.
Note I spared you a cheesey Midi rendition of the tune with same name as the title of this post. Be thankful.
