Chicago's school board voted unanimously late Wednesday to close seven schools and completely re-staff 10 others. WBEZ's education reporter Linda Lutton walks through what happened and what's next. Later on, the guys from the How to do Everything podcast, NPR's Mike Danforth and Ian Chillag, reveal how fans got instant sports scores before dial-up internet and what pedestrians can do to avoid sudden death by speeding cars. And, to mark Black History Month, WBEZ music buffs Tony Sarabia and Richard Steele surprise each other--and listeners--with more deep cuts from African-American musicians.
