We have a late change of plan for tomorrow's volunteer activity. Unfortunately I am unable to attend tomorrow as I am supporting a work client with a critical issue which I cannot delegate to anyone else. I'm hugely grateful to Rupert who has agreed at no notice to lead our group instead. Related to this, the order of tasks for September and October has been reversed and the group will instead be meeting at Alton. We will return to Bridge 70 in October for the task described in last night's message.
