Great photo theonew! Puts into perspective just how big a place the earth is, and also just how small the "world" has become. I believe there is such a thing as "urban survival" that can parallel wilderness survival at times. The biggest point of which is probably being aware of your surroundings.
I've live out in the "county" north of a city of about 130,000. It is the biggest city I've ever lived in or around after growing up in a small town of about 1500 in the most rural parts of Kansas. I have also traveled to NYC numerous times for work as well as Tokyo and London. I can tell you I am more wary of walking around my current city at anytime than the three large ones. No, I would not like living in NYC because I need to be able to see where the sky meets the horizon frequently in order to feel comfortable for long. People were almost always friendly and interesting in these big cities. They are miraculous places to me just for this one fact: it is completely remarkable to me that so many people can live in such a small area and still get along reasonably well. I have been in all parts of NYC and you know what? People smiled back at me when I smiled at them and said hello back when I said hello. There is a bad element no matter where you go, but there are way, way more of us good folk than bad no matter where you go, too. I firmly believe that, even after being a cynical cop of 20 years, brothers!
