Antartica
No, there's one or two out there, I remember hearing something about it but didn't have any interest in it. I guess you could google some shit and try to find out more. I feel like if there are, though, it won't likely get reported on, because other people want that shit even if they can't have it, they're not going to go advertising it.
I don't think you could just go there though, I mean, you probably could but someone might send a small militia out eventually to claim it. I guess your best bet would be to do like that one dude did and build a small island out of plastic bottles and float out to international waters to live.
