On the Road With an Automotive Spy Photographer

Here's what it's like chasing down the cars the automakers don't want you to see just yet. We pick the brain of automotive spy photographer Brian Williams on how that side of the business works and how he gets the shots. Plus we chat with Matthew Guy about air compressors and a wild first weekend of the NASCAR Cup playoffs.

We thanks Brain and Matthew, and Matt Posky for editing. Most of all, we thank you for listening!
