Immigrants and Geography Bee ?

NY Times has a great article on the usefulness of Geography Bee over the more popular Spelling Bee. NY Times articles raises an important point that most of American kids do not look beyond the coasts. This year's winner of the contest is an eighth grader from Illinois, from an immigrant family (Indian in this case). The guys who came in 2nd and 3rd places also happen to be from Immigrant families (Indian again). So just wondering how edgy can, being a child of an Immigrant family, who naturally look beyond the american borders, be? Looking at the winners of the contest, I am tempted to conclude that its pretty big an edge!
