Zone of Contention: The U.S./Mexico Border runs through September 2. It features new and recent works by artists from the U.S., Mexico, and Canada, including David's guest, Greensboro’s Todd Drake. Todd’s new exhibit Help: Hidden Work, Hidden Lives draws a line from the enslaved to the undocumented exposing a repeating history of exploitation. It’s one man’s call to help those struggling for a better life through work and education.
