That beach looks great. I'm more into this kind rather than the Greek ones although Greece has its gems also. I assume though that the water was cold enough to keep anyone out of it, but I haven't even imagined that Denmark has that much sand. It was always in my mind the fact that Denmark, Sweden, Norway=Scandinavia=same land, but seems that I was completely wrong. I only drove through it a bit to a ferry so...
Our neighbour Germans were bathing. I didn't bath for the entire weekend, but I believe it was mostly due to priorities, not due to the cold temperatures.
