Hello,
I am fairly new to this forum but this is the second time that I see this kind of thread.The first was one was about JB and Terry responded with the rights answers.Anyway that was nice to see you recently on our beaches.
You all know that beaches on the Atlantic ocean is a portal of time.What is there today will not be there tomorrow.Now if the discussion is about olds beaches on bays or lakes this is a different story.Like in the ground there is no replenishement.There is not much secrets anymore but they certainly still existent.In that case yes why to give your best spots.
As this thread is concerned it look like the old west.Soon you will have to make your claim for a piece of beach

The real secret is not the location but the knowledge of your equippment and above all knowing when is the time to go.
