SAN ANTONIO — Hundreds of Lanier High School students chanted in support of a man they never met - but feel they know. They're getting ready to march in honor of civil rights leader Cesar Chavez.

"Not only are we representing our school but we're also representing our culture, our raíces. A movement that happened years ago, we're still part of it. It's still alive and it's a big honor," student Rachelle Rangel said.

Chavez's own grandson Andres Chavez will also be attending. He came in from California to serve as the Grand Marshal for Saturday's march. He sees his grandfather in students eyes.

"Young people have always been the leaders in movements, believe it or not,” he said. “My grandpa started when they were young. Martin Luther King started when they were young. So now to see people getting involved is such a breath of fresh air.”

Though for these young people, the cause is different. About 17 students from this high school will lead the march. One for each of those shot to death at a high school in Florida last month.

"Such a sad thing going around in schools. You don't even feel protected anymore,” Lanier High School student Isauro Ramos said. “I feel like this because of this it will have an impact in other schools to have more protection for the students,"

"Us, our younger generation now getting a chance to have voices and be heard and I think that's very special," student Amanda Ybarra said.

For students, Chavez visit brings inspiration.

"Even after so many years, his passion, the Cesar passion of Si Se Puede, you could always fight for him, it's still alive in him," Rangel said. 　

"When the other people are gone it's going to be us young people to take that torch and carry it forward so the sooner we can get started, the more training we can get and then we can be really effective," Chavez said.
