It's nice to know what our founder is up to from time to time. At the end of The World Tonight, 20JUL12, was a piece about a Book Club which planned to meet and discuss whilst walking. Gavin was called, perhaps by phone, to give expert opinion presumably about being en pleine air, since he was introduced as the founder of the CAS. He made some light hearted comments about bumping into trees whilst reading, but was very much in favour of such fresh air discussion not being constrained by eye to eye contact across a table.
