I am just wondering - are the soundings ever heard by anyone in the country - or is it only in the big cities? I live way out in the middle of nowhere and it is very quiet - so quiet that you can hear the cows chewing their cud - but I have never heard anything of the like - no unexplained noises - so I am wondering if this is isolated to city streets and busy nights, and all the the things that relate to "life in the city" or is this happening in other places as well as in the cities?
