Me again - this time looking for 1970s drivers for T&D!

Early '70’s, leave Stoke at 02.00 in an Atki Borderer, with 20 tons bagged salt for Aberdeen docks.
M6 finished at Carlisle, old road all the way to Aberdeen, 12 hours, handball 20 tons salt off, then run back to Glasgow ready to reload next morning, 20 hour day!
Fit as a butchers dog in those days.
