My software developer is going here. Leeches, snakes, spiders, virulent diseases, drug-smugglers - living in Sydney has been good training!
He signed on as communications and meterology guy for an expedition to study the crater. There have only ever been two expeditions there and as yet they've not discovered the origins of it. So he's going on a two month trek into the Amazon rainforest to study a mysterious crater. How cool is that?
I totally reckon he's going to be abducted by aliens.
