Youth Code Jam will have a hands-on activity booth at the PAC Fest event. Come and volunteer with us! About the event: PACfest at Palo Alto College is an official Fiesta® San Antonio event, the largest south of Highway 90, held the Thursday before Fiesta’s Battle of Flowers Parade. This family-friendly event features a main stage with artistic and musical performers throughout the day, food booths, children’s activities, Social Media Alley, and more! Bring your lawn chairs and blankets; this year will be a blast!
