We just returned from San Francisco where one of the highlights was the street art tour we did with Russell - despite the drizzle that day. Communication with Russell via Vayable was easy and he was very flexible about date and time and number of participants. We met him with his bike in front of a cafe and after a brief introduction to San Francisco's history he took us through the streets of the Mission district and showed us a vast selection of different types of murals and graffiti, which we would not have found on our own and definitely not within the limited time we had available. Our favorites were the Edificio de Mujeres and the large black and white Santana mural ... AMAZING ! Russell was super friendly and easy going. Thank you, Russell !
