I don't pass along chain emails, but the photos were horrifically vertigo-inducing, so I did want to share them with others.
But it turned out that when I did a web search on "Stremnaya road" I discovered that there was a big controversy on the real location of the roads in the photos, with claims that the photos were taken in other South American countries, China, and Italy.
Eventually I tracked down a post that seemed to put an end to the controversy. The photos I had received in the email actually came from more than one country. If you want to see the complete set of photos of "The Most Dangerous Roads in the World," you can follow the link.
