Jenn and Kevin Beck are raising their 4-year-old son Gray to become a proud American. On Sunday, the parents from Highlands Ranch had the opportunity to show him what others have done for their country. They took him to The Expo, a family-friendly event during the Warrior Games at the Air Force Academy that allows attendees an up-close-and-personal look at what hundreds of wounded, injured or ill athletes representing various military forces from across the globe go through in their sport. They learn it's not all fun and games. "We want to show him all kinds of athletes," Jenn Beck said.
