[Healeys] Left is right

[Editorgary at aol.com]

At the risk of prolonging this topic overlong, I remember hearing a puzzler 
on Car Talk Radio a few years ago. 

Seems that the archaeologists had discovered the site of a prehistoric 
quarry sight in Britain using infrared photography or some such. From the 
photographs they were able to conclude that even in prehistory, Brits had driven 
on the left. The puzzler was: How did they know that?

The answer, once you hear it is obvious. They noted that at the point where 
the quarry entrance/exit had been, the earth was more compacted on the 
right side of the entrance than on the left. Obviously wagons, tumbrels, or 
whatever they were using to haul the stones arrived empty and left full, so when 
they came in and when they went out, they always drove to the left.

So, Brits have been driving on the left side of the road for longer than 
recorded history.

Imagine that.
