Mr Adams - Why waste our/your time trying to convince us that it is not a done deal? This is another Vera move like the Tram. It will only cost us about 10% of the real cost and then you will shove the remainder down taxpayers' throats with the std excuses:
1) We've started and can't stop now
2) We'll lose this earmarked money
3) We need do to this now before it is too late and the world collapses

Of course, we can build this without any extra taxes (unless you count raiding the general fund to pay for the over amount as a de facto tax.) However, for better streets we'll still need that tax.

Vera really taught you how to get these things done didn't she?
