Ed,
I worked on that beach at Cosmo's and Sands Club for eight years from 79 - 86
I watched the sand come and go. That beach is supported by the morass and balances the pressure of the sea with the flow of fresh water coming from the hills.
It's always in a state of flux.
It's not the beach I first saw in 1969 but it's still there and a certain ways still the same.
You know if you don't like it you don't have to come.
Myself, I live in the hills
