There's the other 5 that are currently in our division that I mentioned to make it at least 8.
Of the teams that we've played recently that aren't in our league that I can also think of: QPR, Burnley, Burton, Peterborough, Yeovil, Barnsley - again just off the top of my head.
I can think of plenty of other grounds where they put the away fans behind a goal: QPR, Wigan, Wednesday, Bolton, Forrest, Huddersfield, Watford. And that's just off the top of my head, so to say that we're the only team that does it is quite frankly bollocks.
