We went to Argentina during May of 2011. It took some getting used to since they take siestas during the day. The restaurants and shops would close and wouldn’t reopen until 8-9pm. They sure consume a lot of meat and wine here.
We took a ferry out to Uruguay. Its such a beautiful, tiny, Spanish town. We arrived in Montevideo which is their capital and got around by cab and foot.
From Argentina we flew out to see Iguazu Falls. Iguazu Falls is the waterfall bordered by Brazil and Argentina. Iguazu Falls has recently made the list of the top new natural wonders of the world. More info. can be found here: http://nature.n7w.com/
