I’m not usually up at 7 on Sunday morning but this morning I was, in the hope that I might get to bed at a reasonably early hour on the eve of my return to work. When I stepped outside to get the paper, everything was absolutely silent. Everything except the incredibly loud rumbling machine noise that filled my ears and seemed to be coming from the direction of the river. The question is this: Is that sound always there- the low roar from the trains, the highway down the street, the remnant of industry around the Mon river? Or was it just that kind of morning?
