Critical Mass
From Seattle Wiki
Critical Mass is a "spontaneous coincidence": a monthly bicycle ride to celebrate cycling and assert cyclists' rights to the road.
Seattle Critical Mass is on the last Friday of each month, rain or shine, 5:30pm at Westlake Center.
Each critical mass there is a group in the u district that leaves red square at 5pm and bikes to westlake center.
For cyclists on the other side of Lake Washington, a Bellevue Critical Mass may be starting soon.
