I've not had a great day so far so cynicism is right up top with me today :o
I'm in the minority but I'd rather have seen them going else where, anywhere.
Don't see any benefit coming up this way and just see it as another excuse for the government to screw a not so few extra quid out of the taxpayer under false pretences. Just take every cost estimate, multiply it by 10, half the benefit for London, stick a big fat zero in for the rest of us and that should be pretty close.
Edit: reading that it's been a worse day than I thought
