I went to Filbert St but I was in the home end above the away section hiding my colours (especially when di canio scored a dodgy pen ) To get a ticket I rang up Leicester, they couldn't believe I was an Australian Leicester fan and were very helpful haha. I couldn't see what you describe because of all the fencing and stuff after the game.
Luton was like that, between terraces, underneath the second floor of one, then up metal stairs over a backyard and into the stand.
I went to Ninian Park too and don't remember seeing much although I had been warned how dodgy it was.
But apart from that.... Brighton, Barnet, and West Ham, that might have been it I think.
