Halloween Critical Mass: Manhattan


Grab a bike, and your scariest costume, and get ready to ride through the streets screaming on the Halloween Critical Mass. Become the positive and "spooky" celebration of what our streets do look like with non-polluting sustainable transportation and community.

Critical Mass meets the last Friday of every month at Union Square Park North. Make sure to bring the appropriate lights and bells.
