What other risk does safe standing introduce? I'm genuinely interested.
I don't understand the argument that because it doesn't recreate an old fashioned terrace that it has no value. There are a significant number of people who prefer to stand while watching football, quite apart from nostalgia for the days when you paid 2/6 to get in and had to stand in a stream of piss from the bloke behind you. If there wasn't a demand for it more widely then it wouldn't be being installed at numerous stadiums around the country and in other places. If it's successful at other clubs then I'd expect more enthusiasm for installing it in at least parts of the north stand.
I haven't said it introduces any other risk. You're the one who seems to live in fear of falling over the seat in front of you.
It seems to me that you're asking Tony Bloom to stump up several million so you can carry on doing what you currently do but with a rail in front of you. Explain to me if I've got that wrong?
