Some San Antonio Taylor Swift fans still may harbor “bad blood” over her decision not to include an Alamo City stop as part of her 2023 Eras tour. However, it’s a sound bet that plenty of Swiftes will be willing to “shake it off” and celebrate their idol at a Taylor Swift-themed dance party in San Marcos this weekend. Doors for Taylor Fest — a gathering “for Swifties by Swifties,” according to its Facebook page — will open 8 p.m.
