Every little girl wanted one, until they found out how hard they are to swim in.

Grand Traverse YMCA Safety Around Water Coordinator Chris Burn bought his daughter a mermaid tail, because it's the latest craze. But he realized that even experienced swimmers had a hard time swimming in them, so he started a swim class specifically for mermaid tails.

He says, with the right experience, they can be used anywhere, but it's important that people know how to safely use them. The classes happen once a month up north - maybe a weekend trip?
