Just got the Impossile Badge following the description of DarkMythos. Thanks! I had to try very often though. I guess best starting point is Cuba. In Greenland you begin spreading very fast, but there seem to be few direct flight contacts to Brazil, which you have to infiltrate quick to reach Peru and Argentina in time (both having no Airports). You reach South America better from Cuba. And you really can't rely on ship contacts. That's why it's so hard to spread to Madagascar. Starting from Madagascar isn't good anyway because it takes so long to spread to another country. And this first infiltrated other region is your second starting point, so the one ship you've waited for so long leaving madagascar also has to hit a good starting country like Greenland, Cuba or New Zealand and that's very improbably.
