Branching out

Well the trees are anyway.  Uneventful day as many are.  Sainsbury's in the morning, walked Murray after lunch and phoned a friend. 
OH received invitation for vaccination. Logging on website to book locations from Cambridge appeared as Bury St Edmunds, Chelmsford, Enfield and other equally ridiculous locations.  Now booked somewhere more local but on the other side of town which isn't clear on the map.  It seems a stash of letters dated 22 February sent out and received 1 March triggered all local bookings! 
Stay safe all.
