Been going on and off since 88, but unfortunately didn't get taken to the Sheff Weds match!
However the Smith goal vs Everton was, for me, a real stand-out moment. I think the atmosphere created by us in the 20 mins or so before Smith scored was something I'd not seen at a home game for a long long time, if ever before. And when the goal came, to me it felt like the fans had really played a part in spurring the team on and getting us back on terms. I'd never really liked The Great Escape chant but it was great how it went on and on and on.
Biggest league away following I've been part of was probably Wigan away in the Dowie era. Nearly 4k? Other than that probably the cup game at Anfield a few years ago.
