Some children of US servicemen killed in combat are giving their late dads a special gift this Father’s Day: a letter telling them how much they still mean to them.

On Father’s Day, Haley Hartwick usually stops by Texas Roadhouse, which was her father’s favorite restaurant, to get a take-out dinner of steak and potatoes. She then likes to go home and watch the movie “Quest for Camelot,” a film they enjoyed watching together.

Memorial Day is a day to reflect and remember those who made the ultimate sacrifice, and for one organization, an opportunity to give back to the loved ones they left behind.

PepsiCo teams with the Children of Fallen Patriots Foundation to spread awareness and raising fund for the families our service members leave behind.

Ryan Lee Gehris joins 'Fox & Friends First' to share his story as he rides his bicycle across America on a mission to raise awareness and money for the children of fallen patriots.
