While in the southwest corner of the state of Paraná, my translator André and I entered into Argentina (we also visited Paraguay-see other entry.) As you can see, the Argentine-U.K. dispute over the Falklands-Las Malvinas still nurses unsettled feelings. We saw this sign in Brazil on the way into Argentina. In fact, for the uninitiated American like me, the whole area has an interesting political history. Just google the War of the Triple Alliance to see what I mean.
