Meeting with Lucia Snyderman and Hannah Bassett as they walked the entire length of the Severn Way long distance footpath. Lucia is doing a PhD funded by the Zoological Society in the history of sturgeons in the Severn estuary/river and their possible recovery.  I shared a few references to sturgeons I have in my many Severn Estuary / river books. We walked out on the Severn Bridge to check out the view, and gaze at the amazing, ever-changing patterns in the tidal waters.
