One place that I think would be cool to visit someday is Russia! I know there are people who enjoy traveling to the country and take a tour of Chernobyl, a city that unfortunately became too toxic to live in due to a nuclear accident that occurred in the 80's. I don't think I'd want to visit that part of the country though, there are certain areas not as toxic but you never know what could happen years later. I know it gets super cold there too, but I love the cold and wintertime.
