Well, I have just returned home after a visit to the big, scary city. What an experience!!! I fail to see how people can live all their lives in that enviroment full of noise and hustle. living at a frantic pace is not for me. They all rush along with their heads down continually watching the clock for fear of being late. At night the sky is lit up like daylight so one cannot see the stars properly. The noise doesn't stop either. Out here in bush, it is so quiet you can hear the stars twinkling at night.
I reckon that given a good horse and a couple of smart sheepdogs I could control their movements pretty well and do away with traffic lights as well. You would just have to get them moving in the right direction, leave one dog with them and move on to the next mob. Too easy.
