Map of Previous Olympic Host Cities

Despite some "disconcerting" signs, the London Olympics were a great success. We've learned that it is much more difficult to plan an Olympiad in a busy city than in the middle of nowhere. We've learned about the remarkable per capita numbers for places like the Bahamas, Trinidad and Tobago and Jamaica, and that there is no such thing as a sure thing at the Olympics, a fact which does not impress Mckayla Maroney. I've looked it up before, but challenged myself to remember as many as Olympic host cities as I could. The results were not pretty. So, I put together a quick little reference map.
I knew it would be, but the cities are awfully Euroasialia-north'mericacentric. Sochi and Rio both represent a significant departure from the traditional areas. Here's hoping for campaigns like Baku 2020(Azerbaijan) and Kenya (2024).  Sadly, Baku has already been dropped.
