Favorite urban walks: the Acropolis of Athens and el Albayzin overlooking the Alhambra at night; Venice and Florence in the morning, El Viejo San Juan and Madrid in the evening, Montmartre and the Pont Neuf when is sunny; La Habana in Sunday; Las Ramblas of Barcelona with some friends; the Brooklyn Bridge in late Spring; Ia at sunset; San Jose at 7:00 A.M.; the Zocalo in D.F. in my twenties; Vieux Montreal when I want to escape...
