I stood for a while watching the big digger loading sand into the buckets of the dumper trucks and it seemed a very coordinated operation, as soon as one left full of sand another arrived ready to be filled.
When we got safely back to the start of our circular walk, the health and safety supervisor asked me how I'd managed to sneak through. I told him we'd come from off the beach and he said he'd have to go and put some signs up there too. I wasn't really in any bother but at least it highlighted his risk assessment hadn't been thorough enough.
I'm not sure exactly what they are doing, making more sand dunes I expect as I have seen them transplanting new areas of marram grass before. I noticed they had a very unusual way to move the picnic benches out of the way.
Before I left to return home I stopped to talk to a lady with a spaniel with the most delightful tail and I couldn't resist asking for a photograph :)
