If you come to San Francisco, be sure to take the Powel-Hyde cable car all the way to the very top of Hyde Street, and get off on Lombard Street. There, you can photograph the city and the Bay, and walk down Little Lombard, the crookedest and cutest street in the world. Besides its curvy way, the street is beautifully landscaped with hydrangeas, roses, and other colorful flowers.
