In case your were wondering the large yellow machine that is going up and down the beach is tilling the sand.  This is required by the FDEP permit for the construction of the Western Walton County Beach Restoration Project. This is a requirement for 3 years after the beach has been renourished. This will be complete prior to May 1st.  It will loosen the sand for sea turtle nesting and softer sand for beachgoers.
