Paraguay

Paraguay is bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest and is the only country in Latin America that's landlocked.  While most urban people speak Spanish, the indigenous language of Guaraní is the more common language amongst the smaller towns.  Guaraní is also the name of the largest Amer-Indian group in South America as well as their currency (one US dollar exchanges at about 3915 Guaranis).
