Excellent posts Animal 👍
I don’t agree with a large part of your conclusions but nevertheless it’s clear that much thought has been given to the subject.
We need more posts like that on here.

I’m just wondering how much of the content is born out of the ugliness of last season ???
Many supporters are still struggling to get over last season - including myself.
The football being dished out at the moment is relatively poor - but again that’s a consequence of the after shocks from last season.
In saying that I believe we have a good future in-front of us with the present leadership.
But it won’t happen overnight.

As for Oakwell.
Because of it’s slightly out of town location I’m not sure how it can be made attractive to customers 7 days per week.
But as a football stadium it’s perfectly placed on the edge of the town centre.

And as a football stadium - I would like to see the North Stand redesigned or totally rebuilt so it joins onto the East Stand at the same height.
Also the West Stand needs rebuilding and joining onto the Ponty at the same height.

Filling in the gaps between the stands with either seats or similar structures to the disability stand will keep the weather out - and keep the atmosphere (sound) in.

As for attendance capacity - IMO it needs to be around 30,000.
Given a prolonged period of success - with home and away supporters we would fill it.
As mentioned in previous threads - no one yet knows the potential of Barnsley Football Club.
We were once a similar size to Burnley, Bolton and Blackburn.
Those clubs have moved forward because they have had prolonged Premier League success.
I wouldn’t want us to be just another Chesterfield, Rotherham or Doncaster.
