High population areas, like cities or big suburbs near cities.
Generally speaking, people in Mass, CT, Jersey, New York are complete a-holes.
People in Vermont or Maine tended not to be.. At least not ten years ago. Perhaps that's changed.
Per example, my car broke down between New Hampshire and Vermont. No less then 11 cars stopped and offered me their cell phone. The 12th vehicle had a guy in a pickup who actually hopped out and fixed the problem for me. I offered him money, and he wouldn't take.
If I break down anywhere near Bridgeport or New Haven, forget about help, you're hoping someone doesn't jack your car. With you in it.
