If you could shoot one place in the world that's not a tourist destination, where would it be?

And why? What makes that place worth traveling to? What makes the potential photos great, or better than what you could get elsewhere?

As a follow-up, are there any places that you've already been to that fit this same description?

I'm getting so tired of going to places that are already overrun by tourists. Would love to see some more authentic places. They don't have to be 'nice' or 'fun' or anything. Just interesting.
