There will be drownings this long weekend.
They don't have to occur. Non-swimmers and poor swimmers going in the water that is waist deep or more should wear a float vest.
Float vests that are designed properly will allow you to move with ease in the water and practice your swimming. Urge your friends who are non or poor swimmers to wear a float vest. Once out of the water, you can easily remove them and get your tan and show off your swimming suit.
