Where should you wish to visit in a hurry?

Here is the reader request:

A friend remarked that on his trip to Cuba, the inclusion of modern buses imported from China had started to erode the charm of the vintage car culture we associate with the island. This is one factor, among many (including the possibility of the embargo being stopped), that made her travel to the island before it changed too much.

What other countries (or cities) are undergoing signficant change and will be presumably very different in a few years from now? Which ones would you travel to if you had the chance now before they underwent that change?

Here is my list of places to visit in a hurry:

1. Cuba

2. Bali, Laos, and Cambodia, which are all losing traditional culture.

3. Any wildlife or game reserve.

4. Yemen (maybe too late already?)

5. Tibet and possibly Bhutan

I can't bring myself to put North Korea on that list.

Here is my list of places which will only get better to visit:

1. China (air pollution will diminish, reading MR might become easier)

2. India (pollution will diminish, sanitation will improve)

3. Greece (someday will be cheaper)

4. Canada, New Zealand, and Australia: they don't have much old stuff anyway and what they do have will be preserved.  The U.S., in contrast, was interesting in the 1950s (or the 1920s) in a way these places were not and many aspects of that period are being lost. 

What suggestions do you have?  Iraq definitely belongs to one list or the other, we just don't know which.
