I think they are somewhere between Santa Barbara and LAX, probably Los Angeles and apparently lost, which is leading to the stress. The wall across the street from them appears to have graffiti though it's too blurry to make out any detail. Over Brendan's shoulder is some kind of brown lattice work thing. I thought it might be elevated light rail tracks at first, but now I just think it's some kind of decorative arbor in a yard. I don't even know if the Los Angeles light rail has any elevated tracks.
