You did better than us in 1984. Took forever to get past Winchester (usual Hockley Lights nightmare) and long slow trek in and particularly out of Sheffield. But there was around 10,000 of us hitting town that day (live on TV then too).
And these days the capacity is under 35k - being first game back up, and full away support, I believe they're still expecting a crowd of under 30k. Around half of our tickets went on the first day of restricted sale so just a shame we couldn't have got more tickets, guess they're holding back the lower tier for home fans in the hope they suddenly get a surge in sales.
