Not had mine yet, despite moving to an entirely different part of the ground. Well, I've moved two seats away!
I was central when I was ESL, almost on the halfway line but I can't think what gangway I was but maybe either 4 or 5?
4 and 5 are either side of the halfway line. Whitey is probably thinking of the layout of the east stand at grove Street not Oakwell
Doing it on gangway was stupid when you had specific Seat and row numbers. We use gangway 3 in the Ponty, walk up the steps and our seats are about 6 in on the right. I was asked what gangway so said 3. She couldn't find it so looked in the 4 box. Lo and behold we're gangway 4 despite never having used it in 20 odd years.
You're lucky. I still don't know which gangway I use. I just walk in on auto pilot to my seat, trying not to step on anyones toes or bump into anyone. I never looked at gangway numbers, lol
