Last year I flew as planned to Buenos Aires from Syracuse, NY in my 1956 G35 Bonanza. What an incredible experience! I spent the months of November and December traveling South America and used the Western route, flew over Cuba to Cartagena, Colombia, then to Cali, Colombia, then to Guayaquil, Ecuador, Trujillo, Peru, Pisco, Peru, Nazca, Peru, Tacna, Peru, Antofagasta, Chile, Santiago, Chile, Puerto Montt, Chile, Bariloche, Argentina, Trelew, Argentina, Mar del Plata, Argentina, Buenos Aires, Argentina and other spots. I did not use agents except for a couple of spots, so I had to learn to deal with immigration, customs, airport police and any other bureaucracy. Planned this trip for a few months and several people helped. Planning to write a book out of it. Gathered A LOT of information. If anybody has questions, I'll be glad to answer. Hans Sturm, a Canadian controller in BC gave me several invaluable tips (most important: bring lots of cash).
