I am sitting in my apartment in Sydney, Australia. My back is to the TV but I am listening to the Boston Red Sox play the Oakland A's.
You can travel to the other side of the world. Drive on the other side of the road. Marvel at exotic animals [and tremble in fear at the site of giant spiders] but how far are we really from home?
When I turn on the tv I can still watch Judge Judy. I must admit I find that 'no nonsense ball buster attitude' of hers to be quite comforting so far from home. In fact, there are a lot of American TV shows that play here in Australia - so if I'd ever like to hear someone that sounds like me without footing the bill to call home all I have to do is turn on the TV.
McDonalds, Burger King [known as Hungry Jack's here], Subway, and KFC bring American "cuisine" to the Australian masses and American expats alike.
Listen to the radio and you'll hear American song after American song. Go to a club and dance to yet another American musical artist. Go to the movies and watch the latest Hollywood flicks.
What if you want to play American sports? There is even a softball league here that I plan on joining when it starts up in September. There are forums and meetup groups dedicated to Americans in Australia. Granted put me in a group of people that I don't know and I get AWKWARD pretty darn fast - but the point is these things do exist - and if I ever have a sudden "I love to meet strangers cause I'm so darn outgoing all the darn time" personality change - I'll be set!
Point is - there is a lot of America in Australia.
