There is a more indirect route using quieter roads, tracks and footpaths taking in the NT's Great Chalfield Manor too. A year or two ago I took the bus from Bradford on Avon to the Courts and took this route back but it is best done in summer when the footpaths are drier.
Yes ... but what the residents are looking for is an efficient way without the need for a private car ("Mum's taxi") to reach civilisation as they know it ... work, education, friends, night out. Great Chalfield Manor is very interest and lovely, but it's not top of many people's lists.
Looking for a comparison elsewhere, the residents of Minehead seek a rail link to the rest of the world. They get a heritage line which is excellent, brings visitors and people to their economy which they are grateful for, but sadly as it stands it does not bring them the trains they want in their daily lives to link them to the world. Oh - Minehead has a far better bus service than Holt.
