John and his 10-year-old son Chase search the streets of Salt Lake City every weekends for the perfect person take to lunch. That they require is that the person is homeless. They started it four years before to share a meal among someone, listen to them and figure out how they can help. Mike Campbell is one of the first people they took to lunch and we are still in touch. John or Chase know they can't solve the homeless problem. They just hope the kindness will go on. "If we have the other people come out and help, people will have a happily life." Chase said.
