Trees are everywhere and seem greener here than in most places and the air is fresh and clean. It doesn’t matter Los Angeles has the dirtiest air in the nation. Fifteen miles north, in Pasadena, you can breathe as the trees caress you. This is indeed such an enchanting place that the railroad Huntingtons, and the Chandlers of The L.A. Times, and the Pattons of young George, Jr., and directors from Standard Oil, and many others built their primary residences here. With these privileged people came not merely a commitment to wealth and power but to culture and education. The Huntington Museum offers art treasures from both Old Europe and New America, and the Norton Simon Museum showcases a collection, anchored by Rubens and Van Gogh, superior to any acquired since World War II. Nearby is the former capital of live theater in the West, The Pasadena Playhouse, still a major venue. Also in the neighborhood is that powerhouse of scientific endeavor, Caltech. Go a little way on the other side of Old Town, the new district of stylish restaurants, shops, and galleries, and you will come upon the Rose Bowl, the Granddaddy of all big-game stadiums. And, of course, rolling through the heart of Pasadena is Colorado Boulevard, primary route of the robust Rose Bowl Parade.
