Anti-social Equestrians.

A local footpath is almost impassable due to all the horse muck on it. It's actually a criminal offence (S.72 1834 Highways Act) to ride or lead a horse on a public footpath but these horse riders think they're above the law. They scream at passing cars to "slow down", even when they're going very slow, yet show no consideration for pedestrians and other road users.
