I found this blogpost from Alexandra Kemp, Vice Chair of North West Norfolk Labour Party, about activism in rural areas. Many similarities with our situation and something to be learnt, I think. The full post can be found here, but the concluding paragraph deserves quoting in full here:
"The countryside is the natural home for Labour. With low pay and low expectations in ex-farming areas, concentrations of older people increasingly reliant on social services, the NHS and public transport, children in poverty, young people looking for work, there is everything to gain."
