Hitched to the Universe It all matters. Be it one person, one bird, or one tree. We are all connected. As John Muir wrote in My First Summer in the Sierra : "As soon as we take one thing by itself, we find it hitched to everything else in the universe." Take care of each other. The sketch is Heart Lake in his beloved Sierra Nevada. You can find this sketch, lovingly polished, in the book Big Ideas Little Pictures.
