Underneath

I've had such a perfect day.
I woke without an alarm clock and the sun was shining.
I caught a bus to St Paul's for my favourite walk along the river
St Paul's -Millenium Bridge - Tate Modern - Southbank - Palace of Westminster - Trafalgar Sq.
The picture is from underneath the Millenium Bridge looking up.
On days like this it is hard to imagine many better places to be in the world than London.
