Rucksack lost in tramore back strand dunnes

Hi There, I lost my rucksack (like a backpack) today early morning in tramore. I was fishing in the back strands near the Dunnes and my rucksack was in the sand but a bit far away from me. When I came back it wasn't there. I think someone took it thinking it was forgotten there. Do you know a place where people use to left these things, like a "lost and found" place? It was a grey/yellow fluorescent rucksack
