For the last year I visited site b only to photograph the perimeter fence. I no longer could find a discrete way in, especially as a lot of houses had been built and sold and were overlooking those gaps and scalable places. Today though there was a corner down the very far end with not only a perfect person-sized gap in the fencing but it was shielded by earth from a deep excavation, so I could go in without expecting security to show up. There are currently a lot of former works going on around that point, where wooden boxes are made ready for concrete to be poured inside to construct walls, and with rebars to provide strength.
