"Nancy and Bryan Lara, ages 10 and 8, knew something was wrong when they saw a tractor surrounded by white clouds near their school bus stop in Caruthers.

'I know that clouds are not on the ground, they're in the sky,' Bryan said.

The children hid behind a row of grapevines, but they could taste the noxious blend of liquid sulfur, gibberellic acid, insecticide and fertilizer as the rig rolled past them, billowing out its chemical cargo.

Moments earlier, the mist had enveloped 17-year-old Carina at another stop about two blocks away."
