Near sell out crowd at my Australian teams ground. On the right, difficult to see under the 20,000 ish crowd, is the hill - yep a grassy embankment. No seat, not even concrete terraces with barriers just a plain old steep grass hill. There are many other grounds just like this in Australia.
No enforced segregation between home /away fans
No fences to stop you running on to the ground.
You can even buy cans of beer.
there are plenty of stewards on hand in case of an emergency and because occasionally there is a drunken idiot or hoon but they are dealt with straight away
It's amazing that being treated like adults produces adult like behavior.
yet us naughty soccer fans must have a seat - nanny state mentality
