Inasmuch as there’s often a lot of litter on the beach either dropped (or, worse, deliberately dumped) by people or washed up by the waves, you can often fill several bags as part of a Skerries Adopt-A-Beach cleanup, but even as you take the bags to the pick-up point you’ll see some more litter and, just like Colombo, you find yourself saying “Just one more thing…” as you nab another villain.
