Thursday: first mapping expedition for a while, but needed to get out of the house despite the poor weather.

There was a gap in the Duxford area along the A505 between Whittlesford and Fowlmere which encompasses the Imperial War Museum complex (not all of which is accessible), and a surprising amount of housing, some new, which is actually part of Duxford. Went a bit further west to capture the hamlet of Crishall Grange, Thriplow public waste recycling centre, and pet cemetery.

Then the weather cleared a bit so I headed south on my bike to Great Chesterford, which I've completed, and with a bit of time to spare for the train back, also did Little Chesterford.
