The "Miss Navajo Nation" contest is not about America's next supermodel, or her aspirations to end world hunger. "Miss America doesn't have to butcher a sheep to win. Our girls do," said Dinah Wauneka, director of the recently completed 2010-2011 Miss Navajo Nation competition. "They wear bathing suits, we don't." The competition for this year's nine Navajo contestants, ranging in age from 19 to 25, was a celebration of the largely outdoor and agricultural-based lifestyle of the most populous tribe of Native Americans on the largest reservation in the country.
