I too was at both. The Sheff Wed however sticks in my mind more. I remember seeing those awful tower blocks connected by walkways just as you enter Sheffield. And for some reason I also remember their meat pies the best I have ever eaten at a football ground.My mate had brought a tennis ball with him and when we all invaded the pitch at the end he smashed it into the net from about 20yards which is more than he ever managed in our Sunday morning league!
I was at Blackpool (3-0, not 4-1 by the way)
