The center of St. Petersburg is about an hour by car north of Sarasota. The old downtown has largely been eclipsed, and much of the city is a sprawling suburb of little interest to the visitor. The downtown includes a large old resort hotel, the city's art museum, and a Salvadore Dali museum based on a private collection. In 2007 I went mostly to visit the art museum, which turned out to be in the midst of a major expansion, so only part fo the permanent collection was available.
