Dude on longboard exits terminal, s8ts down sidewalk toward long-term parking. Rasputin beard, wild black hippie-hair, heavy traveler's backpack slung. I grin; he nods and waves. I'm dragging a carry-on and computer half a mile in 90 degree sun, thinking, I really need to do that.

Two gate changes, whipsawed, lugging same from one end of interminable terminal to the opposite. Some people join gyms; I fly United.
