Hooray for Yorkshire! It's great!
We moved from London to Ilkley (a medium sized town) last year. It has been very easy to adjust to our new lives here and we all seem happier and less stressed than we were in London. We do, however, miss some aspects of London life, but it's only 2.5 hrs away by train, so we do go back every now and again.
We chose to live in a town rather than a small village, as we have young kids and wanted to be able to walk to playgroups/school/the shops/swimming pool etc .... having kids makes it very easy to meet people and make friends and Yorkshire folk are generally very friendly. I think we may have found village life too big of a jump from London!
