Is Ventura County building a wall to keep the rest of us out?

Republican presidential candidate Donald Trump has come under fire for proposing to build a wall along the Mexico border to keep undocumented immigrants from coming into the US. Syndicated columnist Joe Mathews says Ventura County is moving ahead with a similar idea, minus the focus on the undocumented. He says Ventura is trying to build a legal wall along its southern border — in this case, to block out sprawl. In doing so, however, he says the county is not meeting the needs of its residents, its workers or Southern California in general.
