It's almost difficult to believe how quickly and fundamentally the essence of public life in saudi arabia has really changed. The kingdom was now become a routine place for global acts to go on tour. You have high profile sporting events, you've got boxing matches, formula one. And it's not just entertainment - most visible changes are that women can now drive. They don't need to have a guardian to escort them. And we're talking about changes to society. Many people thought it would take generations to materialize. And you can't quite grasp that its just happened in a few years. This isn't the country i used to know.
