Your article on the three beaches was very interesting. There are so many things to see with a little looking.
The one beach I am most familiar with, from the late 1920s, is the beach you refer to as Surfside Beach. This beach and the sand to the off-shore reefs has changed significantly over the years, particularly with each winter storm.
The name, Surfside Beach, however is a new one. This beach from the north to south headlands has been known, since at least 1916 and possibly longer, as Brennan’s Beach.
