Driver comes a cropper in police
chase
Monday, June 25, 2007
It may look like the latest aliens to land on our planet have been
drinking and driving, but these bizarre patterns, discovered in a
corn field in Holland, have a much more mundane explanation.

They were made by a drug user who was attempting to escape from
police in his father's car. The man had been using cocaine.
Four police cars were damaged in a desperate attempt to prevent the
crazed driver from reaching public roads, but they could not save
the crop from irrepairable damage.
In the end, the man was captured when he crashed the car into a
ditch.
