View from the train on the Tazara line between Mbeya and Dar es salaam. Every time the train stopped hundreds of people rushed up to it and started selling fruit and veg (and samosas and kebabs and mobile phone cases and...) through the windows. They didn't much try and sell things to us, but lots of smiling kids waved at us and shouted 'Mzungu!' a lot. That means 'white person' - they're pretty observant, these kids.
