What counts as obscure? I wouldn't consider Beijing to be obscure, but would consider Urumqi and Kashgar (also in China) to be obscure.
I'm hoping people will list specific places they've been, rather than entire countries. The overall goal of the page is to encourage people to think about going to places other than Western Europe for research, study abroad, etc. I agree that major metropolises are not obscure (btw is there a better term that should be used - "obscure" sounds Orientalist - perhaps "out-of-the-way" or "unusual"?)
