"The Chili Queens Chili Cook-Off is a nod to the women who sold hot foods like chili in downtown plazas as early as the 1800s. Tacky costumes are encouraged. A previous winner will give out chili samples throughout the event, which serves as a fundraiser for San Antonio Aids Foundation and Thrive Youth. The cook-off is on Sunday, April 3 from 3 to 8 p.m., and admission is free for attendees ages 18 and older." - Polly Anna Rocha
