I have a question on the flags. How does it work, who makes the call, who changes them, etc, etc.
) and there is no lifeguard on duty anywhere in that area. I know those flags dont just change themselves, so when the call is made to change it to purple or double red, how does that work??? I am thinking if there is "known" marine life in the area, you need to know asap (not 30 mins later). Is the property owner responisble to make the flag change?
