Came across an article about fruit trees in Hungary. Apparently in the
first half of the last century fruit trees were planted along many roads
in Hungary, on the principle that if there were to be trees anyway, they
might as well bring some refreshment to the (at the time) foot-weary
traveller.

Someone was asking: what happened to the trees? Seems that those that
survived were grubbed up, for three sad reasons: First, because even
though at the time they bore excellent fruit without much intervention,
they would now need heavy spraying to achieve the same. Second, because
of the exhaust, which would contaminate the fruit. And third, because
were a single caterpillar to fall on the top of a lorry, it would no
longer be allowed across national borders.

So, no more cherries for free (or plums, or peaches, or apples, or,
apparently, mulberries....)
