When the Temescal Street Fair was founded in 2004, it took up four blocks and drew a crowd of about four thousand people. Ten years later, the festival has expanded to span eleven blocks and annually draws about 15,000 people, so it’s safe to say it’s become one of the neighborhood’s most popular events. This year, Bike East Bay will demonstrate a proposed protected bike lane on the block between 40th and 41st Streets, and on 41 Street, and the East Bay Church of Religious Science will showcase live music and arts and crafts vendors on 41st Street. As always, the festival will feature the very best Temescal has to offer. Food vendors will include Cholita Linda, Bowl’d, Pyeong Chang Tofu House, Tara’s Organic Ice Cream, and Curbside Creamery, and a music stage hosted by new venue Leo’s will feature local bands like the SF Medicine Band, Lagos Roots, MJ Brass Boppers, Fantastic Negrito, and Emeryville Taiko.
