John Hancock Sports and Fitness Expo
Father and son Vince (right) and Myron Hunt signed a wall with a space for each of the more than 22,000 bib numbers in the race. The question posed by Adidas, the sponsor of the wall, is "What are you running for?"
The younger Hunt has run 30 marathons, but this is the first Boston Marathon for his father, 75, who grew up in Lynn and is celebrating his birthday. In response to the question on the wall, Vince Hunt wrote, "To be with my dad."
