Being a geologist means you get to study rocks. But to study them, you have to get them first. This means a lot of geologists travel to very far locations to get them. The most exciting place for me personally was Svalbard, it is an island group in the Arctic not far away from the North Pole. But I guess the cake for going the longest distance to get rock samples goes to those guys who went to the Moon and brought rocks back from there.
