Secret skatepark

I was wandering around the area behind the Custard Factory and heard a curious noise coming out of a warehouse building underneath one of the railway arches. There was an open window; I stuck my head in to see what was going on and saw this.



I'm sure it isn't 'secret' to the many kids who use it, but to me it seemed secret -- the kind of place I would have wanted to go when I was young, had skateboards been invented and had I been able to use one without killing myself...
