As the Ethiopian proverb goes, “When spider webs unite, they can tie up a lion.” Guided by this concept of collective strength, WEBB Party launched in 1990 and has become both the San Antonio AIDS Foundation’s signature fundraiser and one of Fiesta’s wildest outings. As suggested by its title, ¡Última Fiesta! heralds the end of an era as WEBB Party moves to Halloween. Emceed by Crys Stone, the monumental evening includes bites from area eateries, a “Fiesta Flourish” fashion show by designer Agosto Cuellar and performances by local drag stars Sasha Taylor and Nilaya Milan Raven.
