My initial thought was the view from the bridge to Two Tree Island but as I look from my window at the bridge from the other direction there are not many moored boats that line the creek. Unless it was an old pic. Nor are there that many boats off the slipway on the north side of Two Tree. And then there's the clue about learning........
I am with Dan on this one...It does look like Holbrook Creek heading up to the Royal Hospital School...I think!!! (errr that is the view as seen from the shoreline in front of Holbrook Creek looking out towards the Stour!)
