@kqednews: In their second season in the WNBA, the Golden State Valkyries continue to make history and remain a cultural phenomenon. When the Valkyries play at home, Chase Center becomes Ballhalla – a sold-out sea of fans decked out in lavender. Brian Watt spoke with Erin Lim, who documented this fandom in "BOUNCE: The Rise of Women's Professional Sports." They talked about the team's challenging, yet spectacular first season, what feels so different about being at Ballhalla and why being a fan of women's sports is political.
