We stop at the Barbican and acquire a London telephone number for Air Canada as well as registering with BAA Heathrow's flight advisory service - for what that may prove to be worth. The service says it's for UK residents, but one assumes that this is in order to avoid long distance telephone calls and our mobile number is UK. The no fly looks like being extended.
Then a visit to the Guildhall. We've been before but not for years and it's free on Fridays. The most interesting bit is the excavation underneath, showing a partial wall of a Roman arena - now close to 2000 years old but once the scene of gladiatorial combat. There are also art galleries, including a current exhibition of large photographs of the heart of ondon taken from above. As well as the permanent collection, with quite a few royal portraits and Victoriana. A portrait of Victoria herself shows her at 18 - very formal but very young.
