San Francisco has a long tradition of neighborhood fairs and the street fair season ends each year with the Castro Street Fair. The Castro street fair is the city's largest and offers dance music, live music, food and vendors everywhere. It's like pride in October. GayCities has teamed up with the Castro Street Fair to give away great discounts and prizes for everyone who checks in at the fair via the mobile app! Stay tuned for more details leading up to the big day. We are super excited to "get our freak on" with everyone at the 2010 Castro Street Fair, as well as use our app to bring it into the 21st century! See you at the fair!
