At first I heard yelling behind me as I teetered on a railroad overpass taking long night exposures of graffiti on a train. I knew college security was in the parking lot to my back and immediately formed an exit strategy. Then I heard it again. Loud, syncopated curse words. FUCK…..god DAMNit…BITCH. I turned to see a dark form staggering up the sidewalk below, head down. I curled my conspicuous, looming form into a less recognizable shape, and listened and watched as he passed. Drunk? Crazy? Doesn’t matter. Interesting. He kept muttering about a problem he was trying to solve.
