I thought they proved you gain money by getting more in?
As per the survey email:
Will just be the existing seats with some kind of zimmer frame contraption up front no?
Metal to lean on in the middle of winter - nah
Leaving the expense aside (which is probably prohibitive) I thought turning the south into safe standing would be a good idea as part of creating a new group of people who want to create atmosphere. The advantage over the north would be that no existing season ticket holder would have their nose put out of joint if they lose their actual seat and everyone making the move to the south would know what is expected of them and the current divisions would be lost.
But as @Tom Hark Preston Park pointed out it's only the de facto rule. Technically, you're not allowed to stand in the North Stand as it's a designated seating area. Both you and the club could be punished. Also I'm pretty sure there are a few NS inhabitants who would like to see the rules properly enforced.
FWIW one of the questions in the survey is how often do you stand anyway.
That's good, they'll get an idea of the numbers.
