Yes, as did brothers, parents, tiny nieces (who must have been a bit amazed to see SO many people!
Impressions? That it was amusing that Tony Blair (who was in Glasgow to address the Labour Party Spring Conference in the Exhibition & Conference Centre, outside which the main demo was held) altered the timing of his speech to avoid the protest. Next tiem I hear him suggest that he is unworried about public disapproval of his stance, I can have a good laugh (albeit it sort of hollow laughter.)
Numbers here - possibly approx 90.000. And it is widely agreed, that, like many other marches elsewhere, many protesters were people who had never previously attended such a demonstration. Oh, and again like other marches, it was peaceful and trouble-free. (I believe there were 4 arrests.)
