From SFTRU :
DANCE PARTY FUNDRAISER for the San Francisco Transit Riders Union – hosted by our incredibly generous friends at El Rio this Sunday, August 26th.
The fundraiser will take place during El Rio’s “Salsa Sundays” dance party and will be an opportunity for you to meet fellow transit enthusiasts, give a little cash toward the very righteous cause of better public transit for our city, and dance your pants off all at the same time! All proceeds at the door will go toward the San Francisco Transit Riders Union. Please RSVP on our Facebook event page  or by emailing us at firstname.lastname@example.org .
