From the official site:
Tony and Marion Paolo, from Carmel, New York, are the proud parents of two sons, DJ and Brian. The bickering is constant for these lovable New Yorkers.
Tony, 52, is a sanitation worker in New York City. He describes himself as lovable and charismatic and says the most exciting moment of his life was coming to the United States from Italy. Marion, 52, is a proud homemaker who considers herself to be persevering and hard-headed. Marionís pet peeve about Tony is that he lets his sons get away with too much.
DJ, 24, works in title report production. Spontaneous and stubborn, DJ admits to having a fear of heights as well as a big mouth. His brother, Brian, 16, is entering his senior year of high school. Brian is painfully embarrassed by his family and is convinced heís the only sane one in the bunch. Neither son thinks their mother will be able to last long on the race.
No matter how much picking and nagging goes on amongst this foursome, the Paolos are willing to put that aside for the chance to win $1 million.
