Catching hold of a charabanc as it slowly ground past one was a favourite sport of Charlie’s as it enabled an easier progress ! Some drivers would stop and remonstrate with one (I am speaking from personal experience here), others didn’t seem to care. The gradual change to more powerful engines, particularly on lorries, led to the practice dying out.
Charlie loved to do a spot of rowing when he was out for the day, and by all accounts could write another book on rowing and hiring boats (and helping himself on occasion), as we have yet to learn.
