There must have been at least 400 - 500, probably more towards the end.
Last report said a couple of hundred had continued up to Mountjoy Prison.
There was a good reception from many in the centre of Dublin, and of course the expected shouts of "Get a Job!".
Lots of chanting "Whose Streets - Our Streets" and a general atmosphere of fun. While there was a much increased police presence in the centre of town today, the policing of the Critical Mass was pretty chill, confined to just following the people as they snaked their way through the city with lots of people on foot as well, and loads of flyers handed out.
Happy Birthday Critical Mass!!
ps we just heard that reports from London critical mass speak of 1,500 people out on the streets and samba on wheels - nice one! :)
