My home country. I travelled from north to south, ie: Patagonia lakes region, Iguazú Falls, Mendoza, Córdoba, Salta, Jujuy, Peninsula Valdés and meseta. I also lived in Buenos Aires 5 years, where I studied.
I visited Chile on a number of ocassions. Most memorably, for an international AIESEC conference. I love the colorful houses in Valparaiso.
I travelled along Sao Paulo's coastline.
I lived in Canada or 6 months when I was 16. That's me and other Rotary exchange students.
Other than beautiful beaches there is some interesting historical and artistic places to visit in Havana.
