James Baldwin said, "The purpose of art is to lay bare the questions that have been hidden by the answers."

What an apt description of a new art installation at the southern border.

A set of bright pink teeter-totters extend into both the U.S. and Mexico through the barrier between the two countries. Children and adults on both sides of the border can play together, seesawing up and down, their view of one another partially obscured by the vertical steel slats that separate them.
