Anyway, some perspectives of mine about America, mostly from a tour I did of the country last year.
1. I got the impression it was a more outdoorsy country than here, so it may very well be there's more of a ruralist/frontier mindset. For example so many people hunt; people seemed to know their wildlife and look out for it.
2. A populace that's nowhere near as ignorant of other countries as some consider it to be.
3. Cities and towns have very regular layouts, so that wide areas of cities seem to look the same. Though I pretty much knew that in advance, from my geographical researches/special interests.
4. A populace that's much more open and friendly than here. Sometimes a good thing, sometimes not.
5. Religiosity - I noticed first hand how religion was pervasive in people's lives even when they were liberal or from more liberal areas by US standards.
6. Obesity WASN'T something that struck me in a big way (I live in Scotland after all, the country second behind the US in obesity).
7. Sociologically not a country that as a whole I'd like to live in or even return to (except for the sorts of places mentioned in 9). I got the impression I was far more likely, compared to here, to get into trouble with women; trouble with children; trouble with people wishing to take advantage in some way; even trouble with police. In other words, exactly the sorts of interpersonal trouble I do NOT appreciate having.
8. The exaltation of the military, and preferential treatment given to them in society, compared to the UK which fought alongside it in the likes of the Iraq war.
9. New York, Los Angeles and San Francisco, at least, were places that seemed noticeably more tolerant than elsewhere, where I felt much more in my element. It was a shock that I found these places, if anything, friendly. I suspect a handful of other cities I've not been to would, I'd find, probably come into this category.
