Rural Decay

I find it amazing how the rubbish just grows in the countryside. There
must be all kinds of spores in the air, like mushrooms.

Then, after a particularly windy night, followed by a humid and damp
day, the spores germinate and all kinds of things appear.

Empty Coke cans, John Smith Lager cans, Costa Coffee paper cups etc.

Why are these growths always empty though? Maybe it is to reflect the
mental state of the people who discarded them?
