Just outside Tijuana there’s a section of the USA-Mexico border wall that follows very irregular terrain and where, attracted by its curves and steep drops, I’ve taken many pictures. It was there that I decided to photograph the Border Patrol making its nighttime rounds along the winding road in the dark.
