The North/South divide?

[Chico]

You mean the Watford Gap?

People start going a bit soft from the Derby / Stoke parallel downwards.

There's also a West / East divide with people getting progressively more stupid, bigoted and in-bred from around the Pennines Eastward.

Explains a lot about the South-East really.

People start going a bit soft from the Derby / Stoke parallel downwards.

And people start to become backward from Luton upwards.

I guess those in between are the worst of both worlds - backward, soft and boring.
