Oh yeah! You see, it was this island that planes and ships had been crashing on/around for like... forever and ever. But everyone in that area knew it existed and that there was something going on there that was worth studying.
So they'd just keep sending people out there. There were like, world war bunkers - from both wars, I think! And radio towers, and all kinds of mementos from the Japanese and Nazi forces that had been there before us.
Lara knows more about all that, though. All I know is from looking around our campsite and the stories she told us.
