Critical mass happens tonight - at least that's what we're told.
Hundreds of bicyclists ride through the city of San Diego on the last Friday of every month and they don't really pay attention to those silly things called traffic laws.
Our partners at voiceofsandiego.org have covered the event in the past and one of their reporters posted that the event happens Friday, Oct. 30.
If you want to be involved, check out the fountain in Balboa Park after dusk.
