That sounds pretty much it to me Jack. Can't think of many more contenders.... And I guess I haven't thought about it too much either, just casually observed.
One interesting note about,
"sneak around without anyone knowing who you are" (great description
). In the UK you don't have to have ID on you by Law - and in any case, there is no official photo ID part from a passport; driving licenses don't have photos on. Driving a car you don't have to have a license on you or any documentation. If you get stopped by the Police you have 7 days to produce your documents if they ask you to, or if prosecuting - they also don't shine huge lights on you or have a guns ready; no guns even. On the other hand CCTV is getting popular in City Centres. The idea being to prevent inner city crime. Privacy invasion? Hard to say, it really is swings and roundabouts everywhere - plus huge lobby in the UK to prevent having to have photo Id or CCTV, etc; Governments have tried to introduce photo Id (they are now again in the light of 9/11) it's always been resisted. A friend of mine was once working in a Kibbutz. He was young and impressionable. He met a well traveled Jewish Man. He asked him where he'd been, how many Countries, what were they like? He said, "It's the same shiit everywhere, Son".
