Well, rural Norfolk is like a desert in that it is extremely flat countryside - you can see for miles (until you get to a town where you can only see the nearest housing estate!!)
Apart from that, the Norfolk of my childhood can best be described by Mr Fry himself - and I don't think too much has changed. I now live on the Isle of Wight which is another rural outpost of the UK and has many similarities. In between I lived in London for about 15 years, and my husband's a Londoner, so to judge from my own experience I would say the main elements of the rural life are:
parochialism - everyone knows each other, which is nice when you need some help but irritating since everyone knows your business; also lots of people stay in the same area all their lives and have a healthy suspicion for anything 'different' or 'foreign' (for my mother that meant anywhere further away than Norwich!)
awareness of nature and the seasons - you are confronted every day with trees, plants etc and you notice the changing seasons of the year more. Means you feel more in touch with the natural world but also, like Stephen says in 'Moab', you see the yukky side of nature - foxes, headgehogs, pheasants splattered across the road for example.
fatalism - country people, perhaps because they often (like me) come from farming families where for generations your income is dependent on the vagaries of the weather, tend to be fatalistic about life and believe if something is going to happen, it will (Thomas Hardy's novels are a good illustration of this attitude); whereas 'townies' seem to feel more in control of their lives and able to make or prevent things happening.
pace of life - although the industrial revolution has finally penetrated the British countryside most folk like to pretend it hasn't and there's a 'manyana' attitude - if you call out a builder to give you as estimate, he could turn up any time in the next week - in the city there's more competition and so things happen more quickly.
I'm sure there's more, but that's just my impressions....would be interested in other people's...
