Natalia Dominguez, 5, left, and her older sister Valeria, 9, right, both of Greeley, pose for a portrait in the yard behind Al Frente de la Lucha community center, May 1, 2005.   Natalia was born in the U.S. but Valeria was born in Mexico.  During Monday's immigration rights march, Valeria asked her uncle, Fernando Lujan, also of Greeley, if being born in Mexico made her a criminal.
