I watched two things with old factories in over the last few days. Bear Grylls Urban Survivor , where he worked his way down an abandoned industrial building in Eastern Europe (and hunted for rats and ate baked woodlice), and The Ipcress File , where Michael Caine as agent Harry Palmer is held captive by foreign agents. ( The Ipcress File still has incredible swagger. The performance by Nigel Green is phenomenal, I never appreciated just how good previously.) Anyway, these huge, brick built declining old structures are pretty horrible places. They seem to be relics of a different world - and way of being. Sooner or later, everything must be replaced. I wanted to take pictures of factory rooflights this weekend - but everywhere I went there was demolition going on in them - and on a Sunday. I was just about to scale a security fence when seconds before I made the leap a car came around the corner and I was advised not to. Taking pictures from the outside is just not the same, thoug
