hermitcrab we have just faced your problem and dealt with it. We have moved to St Neots, in Cambridgeshire, on the A1 and on the main railway line between London and Edinburgh. It is a town with everything in the town centre, doctors, dentists,opticians, podiatrists, Waitrose, Lidl, M&S Food, Iceland, Nationwide, Post Office, Watersones, Bon Marche, Fat Face, and Cine Centre. You name it and St Neots as it in the town centre.
There are a lot of retirement developments in the town centre and Churchills are about to build another. House prices are reasonable here. certainly lower than where we lived in Oxfordshire.
