Read the excerpt from "My First March.”

"Hey, Mama?” I asked. "How can all these buses be going to the same place we’re going? I’ve never seen a building that could hold this many people.”
"Well, we’re not going to a building,” Mama said. "We’re going to a march today. That means we’ll be walking through the streets all over our nation’s capital.”

Now read the excerpt from "2000 Buses.”

Twenty-one chartered trains,
Ten special airlines,
More cars than one could name

The March for Jobs and Freedom
Equal access, Equal justice,
For all, and not just some
