Colombia
Colombia is a country in South America that is the origin point for the Colombian Cartel. Grand Theft Auto has never had a game take place in Colombia, but chances are the game will never have a player enter that country. The illicit drug SPANK is manufactured here and sent to Liberty City via sea transportation. It is unknown whether other places are affected by SPANK or only Liberty City is targeted, but the answers will probably be revealed in Grand Theft Auto IV.
