Security are apparently on bicycles at this site, we didn’t see any but if you do please send us a photograph.
We did see a faded red Nissan Terrano so keep your eyes peeled if you do take a wander around. It’s not too hard to miss as the bloke tends to gun the diesel engine over the main bridge*, just hide 50ft up within the walkways like we did and the bloke won’t stand a chance.
* the aforementioned bridge, to avoid the security patrols run fast through the pipework gantries.
Big thanks to everyone involved! I’m disappearing for a little while now.
