It’s a very common sight on Algarve beaches, as the tide turns, for people to gather on the beach, digging a heel into the wet sand in a sort of shuffle dance. A lot of scuffling often produces enough molluscs to fill a plastic bottle for a lunch time snack, but there are guys for whom this is a serious business. They stand in the water, often waist deep, in whatever the weather gods throw at them. Treading backwards, they drag the net, hour on hour, for an often paltry reward of shellfish. I’m told it pays well, but I can think of easier ways to make a living. That certainly applies to Cady’s Just One Person from Around the World this week. She tells of an awesome level of commitment.
