The mass itself aims to gather at 6.30 though rarely leaves before 7 (or is it 7.30 some times?)
This month, and probably other months too, some people are inviting each other to a pre-drink or just gathering:
Meet at Bernie Spain Gardens for a drink from 17.30pm and join Critical mass later on.
Upper Ground, SE1 9NW London, United Kingdom
This month, Critical Mass rode a little over 20km from Waterloo Bridge till St George’s Circus.
A video from youtube:
It was very drawn out, but at the same time it was a very busy, well attended night. The vibe was good,the sounds rocked, and numbers were impressive.
There is no collective thought so ignore all these opinions, they are personal and not representative of the mass.
