I got a running injury last November which has taken a long time to heal so I decided I would walk my normal running routes and walk some areas that I don't know or hardly know. I did this on various days until the end of January. Whilst I walked I kept saying to myself, "well I've never seen that before!" For example on one of my routes, there is a small concrete 12" x 4" square post, with a tiny notice on top, I always assumed it was a water board post, I've never actually stopped to read it. In fact, now that I have read it its a small commemoration post for a soldier of the First World War. I also found a similar post a few miles away commemorating a Spitfire pilot who was killed in 1941. I also pass a couple of old forts on the top of Portsdown Hill which was built when Britain was worried that Napolean invading when I walk around the back of them and look closely at their walls I can now get an appreciation about how the designer (Palmerston of 'Palmerston Follies' I believe) built in a system of gun slits to deter anyone getting too close. Down one of the footpaths, set back in a small area of wood I came across a huge metal pipe about 30" across and about 20' high just sticking out of the ground with ivy growing up it. I've been told that under Portsdown Hill there are huge fuel tanks which can feed the ships down below in Portsmouth Harbour, this pipe is some form of a ventilation shaft.
