Bumpless

One further glitch has been added in to my appreciation of historical movies.  Apart from thinking "How unrealistic - they all have good teeth" I have now found myself thinking, every time someone is in a coach, "How unrealistic - the road is so smooth."  In the American colonies, for example, the contract for roadclearing required the contractor to cut all trees on the roadway down to a height of eighteen inches; that was considered fit for purpose. Generally, as one would expect, filmmakers sprinkle snow or dirt over the top of blacktop.
