A Florida city is adding an unusual class to its line-up of summer activities -- a "mermaid" swimming class for kids. Cassie Courchesne, a lifeguard and swim instructor with the City of Palm Coast, will be teaching the four-week Saturday class with sessions in June and July for Palm Coast Parks & Recreation. "I wanted to start the mermaid class to make the dreams of little boys and girls come true all over Palm Coast," Courchesne told WKMG-TV. "Putting on this tail and swimming gracefully through the water allows you to enter a world of fun imagination, and that is so important for children to have." Courchesne said kids will learn various techniques to swim with mermaid tails, which must be provided by their families. P articipants must first demonstrate the ability to swim 50 yards without assistance and float on their backs.
