To each his own, I guess . . . The Daily Mail reports:
A thick layer of pig dung spread across a forest floor has put a stop to youths using an area of woodland as a drink and drugs den.
The unusual, and innovative, approach was taken in Middlesbrough after elderly residents complained about the behaviour of youths in nearby woods.
After the pig manure was put in place pensioners told the council there was 'a slight whiff' but that they would rather have 'a pong than a bong'.
There's more at the link.
I guess the technique relies on the same basic principle as playing classical music to combat anti-social behavior by teens outside shopping malls - only this application of it is, shall we say, olfactory rather than auditory in its deterrent effect?
