We lived near the beach for many years and saw this one time too many. So, instead of being afraid of the ocean be more afraid of the sand. Please don't let your sons dig holes in the sand, at least not deep ones. We have seen children and teenagers have serious accidents or worse with this. The sand collapses into the holes and consequences can be fatal, so just heads up on that. It was also just on the news so I hope a lot of parents watched it. What seems like fun can turn quickly into a serious situation. It was just a known fact in our home..... no deep holes at the beach.
Sorry to be a downer....just want to make sure the boys AND parents enjoy themselves. Do have a good time though!!!
