That is an excellent point. In rural areas such as mine, there are often such signposts. One of the joys of living in the country is that people can set out on those routes. I recommend to everyone the wonderful Ordnance Survey maps, which record everything down almost to the inch. However, in those areas where signposts are missing, I urge local authorities to look at installing them, because they make it much easier for those who wish to use footpaths.
