I used to live near Horncastle, my children went to schools in Woodhall Spa and Alford respectively, what do you want to know? We drove all over the county, everything is far apart so shopping was done just as often in Lincoln as in Boston, Market Rasen or Mabelthorpe. Or pop up to York or down to Grantham, across to Nottingham.
I lived there in a very small village for five years. People were very friendly and welcoming but I'm sure it varies, as does any place you choose. They have buses that you can dial to pick you up. They have time to serve you properly and chat in shops, I suspect it's not much different from living in Wales. In Winter, we used to say 'Lincolnshire is closed for the Winter', but in summer it's beautiful. The beaches (apart from Skeg) are beautiful and empty. It's a cheap place to live in. Still lots of bakers and butchers.
