I'm more interested in the design of the new stadium than the loss of the old one. As long as it's a football stadium first and that isn't compromised to make it multi-purpose then I'm in favour. Access at OT is poor, as it got bigger it got more cramped in its site. Internally more seats meant worse viewing angles.
The romantic in me still hates losing the old ground though - even though it looks nothing like it did when I was a kid (when the cantilever stand as I still call it was state of the art) so I was wondering what would be a fitting echo of it.
I finally realised that if they gave the old pitch area a job that made it a fan space (not as a hotel or a car park!) even the sentimental bit of me could be appeased. They could even leave some of North Stand behind as restaurants, museum, bars etc. The pitch itself? Zone it so you can still see the shape and the position of the lines on the pitch but yeah, give it something(s) to do but somewhere any fan can go.
Apologies for the ramble
