Right I can't post pictures so I'll do my best to describe, the silver shed on the left, half way up, with the darker rectangle on it. With me so far? The halfway line ran across the picture in a straight line continuing from the highest point of that shed.
Think that was the Blackburn one, the following season someone next to me in the North set off a big red one when we scored the first against Bolton in our first win in Division 1, I'm still coughing it up to this day!
