San Antonio residents will vote next year for the biggest education bond in the city's history. The proposed bond issue calls for more than a billion-dollars to make necessary changes at SAISD schools. Parents, teachers and community members have been sounding off on how the money should be spent. They attended a meeting on Monday night that was the seventh of a series of 12. The funds are tentatively allocated to cover renovations at three-dozen schools, improve security, and replace antiquated air conditioning systems.
