Sorry, didn't mean to be away for so long. Thanks for all the repsonses.
Agree, Floss, if it has to be an 'in' place, the answer is no! I am happy with an 'ok, not absolutely fan dabby dosy area' but one with good schools, low crime and a pleasant community. That would be perfect.
Norfolk is lovely but too far north & east. Kent is also too far east. Milton Keynes, no.
So, to be more specific, I suppose I'm thinking Hertfordhsire, maybe Beds & Cambs, west of London, home counties, M4 corridor, Oxfordshire, Southcoast as far as (&including) Dorset.
Bristol & Swindon could be good. But is there a reason people take the piss out of Swindon? Never been so don't know!
