And those fans spent plenty, giving a much-needed boost to the Southern California economy.
Jamie Seymour and her daughter Tara, for example, came all the way out from Louisiana. They're sticking around after the show for a full week, with a trip to Disneyland among their plans. Jamie figures the family will probably end up spending close to $5,000.
And Tara was so happy seeing Swift that she experienced an apparently common phenomenon.
"I just started crying," she said. "I don't even remember it. I blacked out, I think."
Many fans on the current Eras tour, in fact, have reported a form of "post-concert amnesia" from the excitement of seeing Swift in person for the first time.

Local merchants, however, will certainly consider this a tour to remember.
The SoCal economy saw a roughly $320 million boost from Swift's visit, according to an analysis by the The California Center for Jobs & the Economy .
That includes some $45 million in various state and local taxes, including on hotel rooms for fans and on income generated by Swift and her associated businesses on tour. It also includes $160 million for local businesses and an increase in 3,300 jobs.
The average Swift concertgoer is expected to spend more than $1,300 - that's on tickets as well as merchandise, food, lodging and travel expenses.
