Down London...

10am train to London - met with some other teachers for lunch and a wander around City Hall, including down to the Design Museum; then back across town to Clerkenwell and the GeoVation hub of the Ordnance Survey for the pre-launch of our new Mission:Explore book in association with the National Parks. Prosecco, beer and nibbles and a very pleasant event, and then headed back. All going smoothly until we got to Cambridge when a fatality on the line ahead meant a termination of all trains and a very protacted final leg home.
