Milo Ventimiglia, Sophia Bush and Austin Nichols on tour with the USO

On the eve of his second tour, “Heroes” actor Milo Ventimiglia discussed the unique nature of traveling for the USO: “There is nothing that can prepare you for how you feel after participating in a USO tour. It changes you, you’re more aware of the sacrifice of our men and women in uniform and more grateful for their service.“

Joining Ventimiglia on their first USO tour, "One Tree Hill” actors Sophia Bush and Austin Nichols echoed those sentiments.  “Being there visiting the troops and their families has been an incredible experience,” said Bush. “It is an honor to lend our support and extend our thanks to these exceptional men and women.”
