La Expo 92 fue lo más grande que le ha pasado a Sevilla, yo tenía 10 años y fui con el pasaporte de sellos casi todos los fines de semana. Todavía lo guardo.
Impresiona ver que París hizo cinco en el siglo XIX y principios del XX. Y luego España tiene tres: Barcelona dos veces y Sevilla.
Fui a la de Osaka 2025 y las colas eran de locos, pero el anillo de madera merece la pena solo por verlo.
