I used to do over 300 miles a day as a service engineer and hardly ever left Lancashire, for some reason if I was in the South of Manchester, (I don't call it Greater Manchester, it's still part of Lancashire to me), my next call would be say Colne and just as I arrived in Colne my next call would be less than two miles from the job I had just left in Manchester.
This is how the day would go on and the miles spent on the local motorways soon mounted up.
