Finally, all over the world, you generally find where explorers in small groups are passing through - Lewis and Clark, the Hudson’s Bay/Northwest Company explorers, Magellan, Pizzaro, the explorers in Asia and Africa - small nomadic cultures are happy to greet foreigners and help them and let them pass. These cultures are more likely to be hostile to their neighbours, rivals for local resources, than to someone who is small in number and no threat to take away their livilihood. They are instead a novelty whose visit should be enjoyed.
