Ivor, as Sarah has said, roads in Lincs are appalling. Getting from one end of the county to the other can take hours- something to bear in mind.
Also jobs are not thick on the ground and salaries are appalling.
What did it for me was just the total lack of opportunity for my DD who was only 3 when we left. There is really nothing for kids to do unless their parents are prepared to drive them everywhere. I cried when we left- with happiness! XH was so stubborn about going back even though we knew it was a mistake within months so had to sit it out for 4 years until he had a reality check.
I was born and raised in London, but wouldn't go back (can't afford it and both DP and I work south of London). I currently live in Hove and to me that offers everything I want. Great shopping and social life and only 10 mins drive to the South Downs which is beautiful. I do far more walking down here than I did in Lincolnshire. I am not a die hard townie by any means, I am a keen horse rider and like getting out in the country, but that is very different to living there.
I had similar rose tinted ideas of what country life was like but I can tell you as a die hard southerner I really struggled in Lincolnshire. My mother's family come from up there so I knew the area well (or so I thought). My country living stint nearly cost me my sanity and definitely my marriage.
I know its horses for courses, but you really need to think about what is in it for you- and no, crocheting and making jam ain't going to happen!
Will stop rambling, but I just don't want you or anyone to learn the very very hard way as I did.
