I don't know what GFC is. I'm sorry.
It's a common thing here to call it "America" as well. I was on another forum and it caused quite a big "battle" because it was seen as disrespectful and arrogant (by the Canadian and Mexican posters) that the U.S. citizens called themselves American's. As if they (we) thought we were the only ones that mattered.
ANYWAY! I hope that you enjoy your trip! There are many good and wonderful things to see and wonderful people to meet.
I hope to someday go to Australia. For some reason, since my 10 year old was born, I've always wanted to take him there.
