Russell is an excellent guide with a wealth of information about street art, its creators, and its intricate history. He actually wrote a book about it! Russell gracefully navigates through SF's Tenderloin and SoMa neighborhoods and points out the beauty sprouting out from the darkest corners, streets, and alleys. I personally have been looking forward to taking this trip for several years, but have never gotten around to taking it. Russell and the art he showcased definitely did not disappoint. I took a private trip, and it was wonderful. He gives you a new, beautiful perspective to the city. With so much going on, it's easy to miss many of the artistic wonders that are right in front of your eyes. Russell points them out for you. I took a two-hour tour, which I thought would be more than enough. It barely skimmed the surface! I could have easily continued happily for an additional two hours! Russell knows such intricate detail and history about the artwork and the artists behind them, that with all the information he shares, you almost want to take out a notebook and take notes to reference later! However, there's no need to take the trouble to do so! Why? Russell provides you with a link to a map of the places visited during the tour, as well as an email list of all the artists, and additional galleries and websites of interest. I really considered that above and beyond! I highly recommend this tour!
