That reminds me of some thing I hadn't thought of in a while. In 2001 I worked in an area near a major airport. In fact, our building lined up with one of the runways. So commercial jets were constantly going overhead. In the days following the 9/11 attacks, all air traffic in the US had been suspended. The silence, while nice, was very eerie. While the rest of the surrounding were not as peaceful as yours, I think I know what you mean.
