  Benzol: And I thought his name was just Oscar Castro.
Jul-20-05  Caissanist: Actually his name is rather short for a Latino. Every Spaniard or Latin American has at least two last names, and some have three or even four.
Aug-20-05  morphynoman2: SOrry, but in Colombia nobody call him Castro-Rojas. He is, as Benzol say, just Oscar Castro.
Mar-30-06  Caissanist: A thorough explanation of the Latino double last name thing was recently posted on the Francisco Vallejo-Pons page.
