The man who often led the city’s César Chávez March for Justice was in the hospital Saturday fighting cancer, and no Hollywood film this year gave the annual event an added boost of participants. […] a big crowd assembled at Guadalupe and South Brazos streets under cloudless skies Saturday morning and marched to the Alamo in honor of Chávez and his legacy of fighting for social change. Some marchers Saturday carried portraits of Chávez or signs and flags with the United Farm Workers logo. “César Chávez had a history of justice for everyone, equality for everyone, and I want to instill in my nephews, my daughter and my grandson that fighting for justice is the right thing to do,” Garza said. More than 80 students from KIPP San Antonio charter schools marched, some carrying signs with a Chávez quote: “You cannot uneducate the person who has learned to read.” Some students affiliated with Somos MAS, an organization promoting Mexican-American studies programs, carried signs that read, “Remove the chancellor.”
