‘Digging your own grave’: Maryland lifeguards warn of the hidden danger of beach sand

Lifeguards in Ocean City, Maryland, will begin an intensive eight-day training academy this week to prepare for big crowds on Memorial Day weekend. Before swimmers hit the shore, the beach patrol is reminding them of a rule that’s posted on all of the lifeguard stands: don’t dig deep holes. “You could be digging and suddenly without warning, it can all just give way and pile in,” said Ocean City Beach Patrol Captain Butch Arbin.
