From SFBC:

Current SF Bicycle Coalition members are invited to join a bike ride up and down 2nd Street to take a look at the city’s proposed redesign for 2nd Street. The city is looking for feedback on the one-way cycletrack option for 2nd Street and we invite our current members on this ride to learn more about the proposal and give us your feedback. See sfbike.org/2ndstreet for more information.
