One thought I had while seeing the tents covered in snow on the news - the USA is practically the only place I can think of where people who have a place to live would deliberately sleep in a tent during a snow storm just to prove a point.
All over the world, Turkey for example, people are forced to sleep in tents often with 10 or more people to a tent, because of the earthquake in this example. People on Haiti are still sleeping in tents and have no home to go to once this "protest" is over. And I am sure that there are many other places where a tent would be considered luxury and these people think they are roughing it.
Crazy world we live in, isn't it?
