Austin I-S-D held its annual Back to School Bash, Saturday, at the Austin Convention Center. Hundreds of people were lined up before the doors opened. 2700 free backpacks were given away, in addition to hundreds of free vaccinations and child booster seats. Organizers say it's a community effort to put the event on. "We have so many local non-profit organizations that are working together all under one roof providing these resources to parents that normally we would not have in place," said Antonio Lujan, with AISD, "We even provide services in Spanish for our Spanish speaking community." Organizers say the event is a fun way to educate students and parents about the services AISD offers.
