I had a look at Turku, it looks a beautiful city.
It transpires there are people in the UK mooning, too. You go and look at countries on Streetview, and the streets in their towns and cities. Or in the galleries of Streetview sightings dotted around the web. And some places have proved a lot more than others that somewhere down the line, they have a significant amount of oafs.
And it's always the most liberal places, I mean like Canada, Netherlands, Sweden..... what annoys me is these are the sort of countries that are lauded as being good societies, as good as you'll find. I think not. I haven't come across nearly as much of this oafishness from America, especially not the red states - but even within America the rude gestures come above all from famously liberal places. I'm personally really far left but it's in things like this I have a lot of respect for conservative people/societies.
