Rising bollards, Lewis and other hazards

I was due at 2pm to run a session at Merton for political philosophers and ethicists from various US universities. Running late I found my way blocked by filming of Lewis…. I'm not sure who is actually in this TV series so may well have missed the man himself and just got some passers-by or cameramen…

The session went well, Merton is lovely, what a paradise of privilege.
