Little bit of a chicken and egg situation. If the first tractor ever on the beach was there to clear rocks. How did the first rocks get there? A case could perhaps be made that the rocks predate the equipment that was summoned to deal with the rocks.

Some of the posters below you seem to have that annoying expat paternalistic tone of "saving" the local residents from themselves. "I am a long timer here, and I know better than the people who've been here for generations." Ugh.

We all love a sandy beach. The town depends on people coming here to enjoy a sandy beach. The townsfolk need to keep their beach attractive to visitors, their income depends on it.
