What a crazy thing to name such a wonderful park after! I think maybe they call it like that because of how dangerous the wilderness (like the waterfalls, for example) can be to those who are not careful, as in an imminent danger to those who don't belong. But that's just my imagination :P
"Imagine there's no heaven
It's easy if you try
No hell below us
Above us only sky
Imagine all the people living for today"
