Most reviews of this tour are quite positive. Our guide was Gabe, the owner, who said that he normally doesn't do the tours anymore, but no one else was available. Too bad. I commend him for the concept of the tour. But I didn't care who he knew personally, or all the names he threw out that I would never remember, but as long as he knew all this info, wouldn't it have been nice to have a hand-out in case I wanted to find other examples of a particular artist's work. We spent too much time standing in one spot or another while he pontificated on the politics of graffiti. I would have rather seen more. Too bad another guide wasn't available.
