If you read my account of last year's march, you'll know that as, generally speaking, a non-activist, I found it quite enjoyable. If you fancy coming along this time, it would be good to see you there, and good numbers will help to sway public opinion. As far as I can tell, support for a "Yes" is higher than most of the media would have you believe, but still trails a "No". However, about a third of people are still in the “Don’t Know” camp, so visible public support does matter. Poll reporting is often phrased in a way that may encourage you to assume the “Don’t Know”s support a “No”; make sure you check the actual numbers. If you support Scottish independence, don’t let the Catalans put you to shame!
