American airports are a pain. I lived in the US for about two years. Dealt with every government department from the DMV to TSA and Homeland security. All in the day to day of being a foreign national. None were much worse than dealing with local government here. What i would most like to say is that the normal american is one of the warmest and most welcoming people i have met in my global travels. I was invited into homes and social groups freely and warmly. Their views of Australia were as coloured as mine of America. Half my joy in being there was working through all of that. I would have stayed longer had their political system not been so screwed. Unfortunately i kinda feel ours is just as pooched. Hug an American today. They hug back
