"What surprises the British tourists is that, in areas of the US that look and feel like suburban Britain, there is simply less crime and much less violent crime.
Doors are left unlocked, public telephones unbroken.

I have never seen a group of drunk young people in the entire six years I have lived here. I travel a lot and not always to the better parts of town."
