Importantly, these changes come into effect this Monday, 26 October. A number of users may not use the Internet so perhaps those who read this can alert friends and neighbours to the changes.
Why this has been sprung on us at such short notice and with no consultation about the new times is unclear. Lynette and I took Derbyshire County Council public transport questionnaires around the village homes last November and returned them to Matlock. I am not aware anything has been shared with the village since then.
There is a history to this which I will relate at another time.
