Scotland 'split' with six months to go
It's not often I'm going to say this, but I've been hanging around street corners in Edinburgh.
The reason was to meet up with a group of voluntary canvassers from the Yes Scotland campaign for independence.
I tagged along as they made their way up a road knocking on doors.
After, I was told by the organiser that there was a rough 50/50 split between yes and no with plenty of "don't knows" in the street.
The point of the canvassing is to try to persuade people to support independence but it's a vital piece of intelligence gathering as well.
Those who aren't sure will be getting another knock on their doors from Yes Scotland before September.
One of the debates is how big the chunk of "don't knows" is. A Labour MSP told me it could be as high as 30%.
Others say it's not just the "don't knows" which will be crucial but those who can be turned in either direction. The fight for votes will go right to the last minute.
The Yes Scotland camp has ratcheted things up this week with its biggest spend yet on posters and newspaper advertising. They won't say how much has been spent.
They claim to be winning the grassroots campaign with their army of volunteers, although the Better Together camp supporting the union claim to be community-based as well as a badge of honour.
Many of the headlines in Scotland this week have been about what the three Unionist parties will offer Scottish devolution in the event of a "no" vote.
The former Prime Minister Gordon Brown gave a speech saying the Scottish Government should have control of around 40% of its revenue and within that greater control of income tax.
A key moment in the campaign comes later this month when Labour announces what extra powers it's prepared to give Scotland if the country votes no and it wins the General Election.
The Lib Dems have already made their pitch - the Tories will come in last in May.
There will inevitably be differences and I'd expect Yes Scotland to focus on those differences.
The kind of comments I heard a number of times from the nationalists was that the only way to guarantee more powers for Scotland was to vote for independence, otherwise they claim it will be like 1979 all over again when promises were said to have been made to Scotland but not delivered by Westminster.
