Ahhh i went with some mates to chelsea bridge and a few of our mates were on this run so we waited at the "underground roundabout"
i saw 2 coops went to get mine as i was parked just off of the roundabout and by the time i got back onto the roundabout everyone was queueing up to leave i did drive across a set of lights where i saw a coop to the right of me who looked as i looked excited - pointing etc.
I think i am going to join the website and keep an eye for future runs and meet a few other peeps
