every year on the 9/11 anniversary, we take volunteers from new york and send them to some part of the country where they had a disaster and help folks rebuild. >> people in the town told us the tallest thing here is a corn silo. it's a culture shock. >> rebuilding homes or churches or barns, it's our way to say thank you. now more than half our volunteers are not from new york. people from all the small towns we have helped, they keep showing up to help the next community. they're from louisiana and california and indiana and illinois. every year, you see more t-shirts from more locations. >> we're going to pitch in as much as we can. >> after katrina, we jumped on his bandwagon. this paying it forward thing is contagious. >> like this big dysfunctional family reunion of all these disaster survivors who get together and do a barn raising. >> it's the relationships that help you heal. >> it's about using the 9/11 anniversary to celebrate the volunteer spirit. >> we'll see you all next year.
