It is 12:21 and I am on an ADO air conditioned bus now a few blocks from the terminal, en route to Playa del Carmen. This is the first time there are others from outside of Mexico, but the bus was nearly full when I boarded so I am not within speaking distance of any of them. The man beside me kept the aisle seat, keeping me from any conversation. So, again, I watch the roads and I write. Only this time I write on the iPad keyboard on my lap rather than with my thumbs on the iPhone. My hand-carry bag is my lap desk.
