Wondering about all this reminds me of some conversations with my European friends back in graduate school. From their experiences in the SF bay area they would make generalizations for the US. For example, they would lament the lack of public transit in the United States. But I would counter; the east coast indeed has perfectly functional public transportation! On a geologic field trip to Utah my Dutch friends were convinced that all of the US outside of the SF bay area featured cuisine like that found in rural Utah. I recall often feeling the need to explain and defend what might be representative of the US. Despite my earnest explanations, I don’t think they ever really believed me.
Perhaps Australians would feel the need to defend some of the generalizations that I’m starting to make. The Aussie washing machines are constantly off-balance and the garlic presses only give 60% yield of garlic. Maybe the Bruce highway really has more than two lanes somewhere -- but I don’t believe it.
