Gate 30 sits at the very end of SFO’s terminal one. Beyond the restaurants, recharging stations and other conveniences offered to travelers in transition. It is safe to say this is the farthest you can go without actually being airborne. While I wait for my vacation to begin, I gaze through the wall of windows before me. Planes glide across the view like graceful aquarium fish. I wonder what kind of fish I’ll get. Maybe a filet-o-fish.
