I’m in Tijuana on a secret mission. I woke up at 4:30 am, left at 5:10 am, got here just before 8 am. Presumably (hopefully?) the secret mission will be fulfilled within a few hours, or at the very least by tomorrow morning. I haven’t been to Tijuana since the late ’90s. It used to be a bit skanky and squalid; now it feels almost as tidy and corporatized as any mid-sized American city. To some Mexico might seem a bit exotic in a vaguely odorous way, but if you’ve just come back from Vietnam it feels like home turf. I’m sitting in a nice upscale restaurant called Marenca (Jose Clemente Orozco 70, Centro, 22000 Tijuana), and they have good complimentary wifi.
