In reply to Ennerdaleblonde:
I lived in Broomhill when I first moved to Sheffield, so like you, I spent a lot of time on Red Lane around the mid ‘80s. There was a similar wall on Mushroom Lane by Crookes Valley Park which was ok until the council pointed it. I’m sure I remember a very uninspiring natural wall in Endcliffe park which was usually gopping wet.
Memories of the Al Rouse wall are a bit hazy, apart from Andy Pollitt seemingly spending whole days doing pull ups and hangs off screw on edges. The wall itself was a bit rubbish from what I remember, but that’s how they were I guess until the Foundry and The Edge opened.
