Jeremy Hart played with Hot Wheels as a kid, but he eventually grew out of them, tucking the miniature cars away in a toolbox. Then nostalgia struck when he attended the Hot Wheels convention in California with his son three years ago. “I get these little glimmers and glimpses of memories and feelings when I look and see those Hot Wheels from my childhood,” Hart said. Today, the 48-year-old has fully embraced his inner child.
