From SFBC:
The Good Roads Crew thrives on civic action, and where better than the Civic Center along the upcoming Sunday Streets route? Help find and report potholes and cracks to keep everyone safe on the streets. Stops include the Tenderloin National Forest and Boedekker Park. First-timers always welcome (and they get first chance with the paint). Drinks and lunch follow. Contact neal@sfbike.org for more info.
