That middle-aged man walking around Texas Motor Speedway appearing to be an oversized Prilosec pill about to burst out of its capsule was actually Larry the Cable Guy.Larry, of course, is a spokesman for the heartburn medication, but he showed up to the track with another medical device: a neck brace.
