As if to continue this celebration of the return of spring, some places let loose in vibrant secular festivals. One of the most exuberant and colorful is in Spain: Sevilla’s gigantic Spring [April] Fair. Throughout southern Spain, a region so expert at fiestas and romance, cities like Sevilla greet each spring with a festival for all ages. For seven days each April it seems much of Sevilla is packed into its vast fairgrounds. Each striped tent is the party zone of a particular family, club, or association.
