With terraces you stood with your mates and your mates mates - who then became your mates.
Do you even know the names of the blues around you sat there?
That's why people go off and seek their mates at half time.
And there in lies the crux of the atmosphere debate.
They need a re-think if they want to get atmospheres around all grounds going.
They could start with finding a way to let mates stand together.
Mates who meet up together and drink together beforehand and then go to different sections ad sit down with strangers.
They also need to make it affordable for a younger demographic.
They need a core of 18-30 year old males. And I don't want to sound sexist about that.
If they could address these two things alone, I think you would go some way to restoring a decent atmosphere at most grounds.
There have been a lot of other very credible suggestions made also particularly by the 1894 group,
but I see the two suggestions above as being the starting point.
I think also, in the interest of future safety etc., and not wanting to see a return to laddish/anti-social behaviour or plain hooliganism,
then you need an element of self policing amongst the core crowd. I read decent suggestions in the atmosphere thread about how that could
be controlled by official fan groups. So I don't think any of this is undo-able, as long as the will is there from the clubs.
