In the distance, boats moved up- and downriver. The Quinlans had sailboats, with proper triangular-sail designs, which I could see tacking back and forth as they crossed the river northward, or in beam reach as they headed up- or downriver. I noticed, though, that there was a lot more downriver traffic. I wondered if they tended to go back upriver by circling around on one of the other main rivers. That would certainly be easier, if a little more roundabout.
