It is difficult to think of a more mysterious example of fly-tipping than one that has occurred along the scenic coast road between Glenarm and Ballygally.
Someone emptied a number of milk cartons - all of them still in date - on the rocky foreshore, leaving locals scratching their heads over why they did it.
Did someone think the dairy product might lure a school of catfish to the Antrim coast, or had a milkman, late on his morning round, taken a corner too quickly, shedding part of his load? Another theory is a hospitality outlet dumping the milk after the Christmas shutdown.
However, none of the above seems to hold water. But, on the bright side, these could prove to be the most expensive cartons of milk in history.
For a dairy business has offered a £500 reward for information leading to the identification of those responsible for the fly-tipping, and a DUP councillor has pledged to match that figure.
Getting your hands on that reward would be a grand way to bring in the new year and would leave you grinning like the cat that got the cream.
