Always use a red light emitting flashlight on the beach, these are available on the Internet and show a picture,
I think I have sent you pictures of the ones I know about.
Keep lights that can be seen from beach turned off
Fill in your holes and smooth out your sandcastles for the night
Take your “stuff” off the beach when you leave
Put your trash in the trash bins provided
Report any seen sea turtle activity to the Walton County Sheriff
