Thousands of people expected at Houston March For Our Lives

It's no easy task to get a moment to talk to organizers Steven Garza or Marcel McClinton. After all, it's almost 'go time' and they are the ones trying to make this march go.

"I haven't seen a movement like this since as long as I've been alive." said McClinton in between phone calls. Granted, he's sixteen years old but a lot of children his age have been galvanized by the school shooting in Parkland, Fla. It wasn't the first or the worst, but for some reason that was the last straw.

Garza and McClinton say the Houston-area effort is 90 percent student organized and led.

"Of course, we don't have the answers to everything," said Garza. "We need some assistance but what I'm really proud of is all the student participation.Hundreds of kids from Katy to Galveston."

Actually, the organizers hope to do better than that. They think they can bring in more than 20,000 supporters plus plenty of politicians.

Houston Mayor Sylvester Turner is scheduled to speak at the event. Marching is a time-honored means of protesting but it's doesn't always bring change. But the students are young and optimistic and they might not fully grasp what they are up against.

"I think this time, it's it," added McClinton. "This is the last time we are going to have to march. We're not going to have to march next year on the 24th. We shouldn't."
