Its not big and its not funny

As kids we used to trek to and fro across the main brine supply pipelines (big aren't they) across the old river weaver water course all the time - most of the pipelines have been demolished now but this ones still in place as its close to the main works.
Brought back loads of memories scurrying across them, but it feels alot more dangerous nowadays probably because as a kid we thought we were indestructable but now we think its going to hurt for a bit longer now if we come a cropper haha
