Think my favourite litter-related story of (I think) last year was when some wise guy set up a cheapo gazebo in Stanmer Park, had a bit of a chavfest with his chav family and friends and then left the whole kaboodle behind for somebody else to clear up, including the cheapo gazebo. Sadly/Happily he left the receipt for the cheapo gazebo behind, was subsequently traced and fined
I think it was also reported he had to go back and clear up.
