I grew up in Norfolk, still do lots of work there, holiday there and have parents, siblings, nieces and nephews there. I love the landscape, the quirky community init iatives, the peace and quiet, and the holiday-visitor-orientated shops. There are some great pubs, fantastic cafes, and good days out. But I can get better fresh small-bakery bread more readily in London than I can in many Norfolk villages, ditto good quality meat and veg!
I love the N Norfolk coast - good for painters, birdwatchers and those who are happy to make their own entertainment in all weathers (me!). Terrible for culture (as is most of Norfolk - including Norwich, compared to most cities), public transport, and it can be hard to access certain services. Children who need to attend special schools spend hours in taxis travelling in to Norwich, for example.
If you want to live in the most beautiful wild isolated coastal areas, your best bet might be to live along the Huns'ton to Sheringham stretch and work at King's Lynn - or one of the small 'cottage' hospitals such as Kelling. The coastal villages have a good service on the Coasthopper bus - but even one village inland, like Langham, has a very sparse bus service, no shop, no post office, etc. Though it has a good village school.
Rural Deprivation has tangible realities, and many teens are reduced to taking drugs in bus shelters, driving illegally souped up cars too fast on narrow winding roads, and becoming disaffected by boredom, lack of jobs and housing bumped up by second home prices.
There are many lovely people in Norfolk, obviously, but many areas do seem to have a high proportion of people who are not au fait with life in a multi-cultural, multi-racial age. My sister is a TA in a school in North Walsham and is shocked on an almost daily basis by the casual racism of parents and the parochial nature of thinking. My Mum has non-white grandchildren and has had numerous ignorant and rude comments passed her way. But that is not to say that people are aggressive or unfriendly to individuals, just haven't caught up, or had the experience of living in a mixed demography.
It's a huge county, made bigger by the distinct regions and slow transpot routes - you surely aren't thinking of moving there without visiting, staying there a bit, scoping it out? Take a cottage for a month in the area you you think you fancy (maybe as a house swap or something), do the potential journey to work a few times, and experience all the facilities.
I love Norfolk, but I suspect that with Norwich and County Councils having to make even more swinging cuts in the next 3 years, life could get pretty bleak in some ways.
