Brooklyn Critical Mass: Tonight

Calling all biking Billburgers:  Brooklyn Critical Mass will start tonight at 7pm at Grand Army Plaza.

From Time's Up!:

Critical Mass is a monthly celebration of bicycles and other nonpolluting means of transportation, exercising our right to the road.  Critical Mass is a movement, not an organization; no two riders participate for exactly the same reason... Come out and join Critical Mass in Brooklyn.  Celebrate cycling, and assert your right to the road -- Brooklyn style!
