If our demographic oracles are correct, hardly any of you have children. But for those who do, and whose kids go to public school and might need a little extra help, listen up: The SF School Board is voting at its regular meeting tonight whether or not to cut all summer school programs except those for high school seniors who need to fulfill a few last requirements to graduate. They've got a $113 million budget problem to deal with, and summer school's going to be the first to get cut (besides, like, arts education and theater and all that we hold dear). This is bad news for some parents, but excellent news for most kids, we suspect. The agenda is here and the meeting's at 6 p.m. at 555 Franklin Street.
