This beach was loaded with driftwood and some clever people have built all these shelters out of the wood that is washed ashore. Here you see one of them far away.
And, here is a close-up of that very structure. You could actually sit inside one of these if you wanted to. I personally, would not. They didn't seem that structurally sound. When I was a kid it wouldn't have bothered me one bit! Funny how the older we get the less brave we become. Ah...to be a child once again.
