I found this on Trip Advisor. This is how and why some people get in trouble in the water.
The first day we headed down to the beach for just an hour or so-forgot all about the flag system in our excitement to be at the beach. there was no flag directly in front of our condo and there were lots of people in the water. My husband did go out a little far and came back in and said he almost got pulled out there and was scared because he was afraid he wouldnt make it in.
