 Well, summer often includes beach trips, and while the ocean is generally a friendly place for swimmers, there are sometimes hazards, as our next guest knows well. His name is Wyatt Werneth, and he's a lifeguard instructor and trainer and a spokesman for the American Lifeguard Association. He joins us now on the Patriot Mobile Show hotline to discuss how to enjoy swimming safely. Wyatt, it's nice to have you as a guest, especially because I'm on a vacation spot on the Atlantic Ocean in southwestern France, where, as a former lifeguard, I know there are some very powerful riptides. So what exactly can happen in a riptide, and how do you protect yourself against them?
