My son-in-law, his family of four children and his wife and to three other couples with their children were out at Keystone Lake on Saturday August 28th. My son in law passed away due to drowning at Jellystone Park that Saturday. The lifeguards didn't know what to do and they had a hard time getting back to shore. The ambulance took 40 minutes to get there by the time they got to the hospital they tried to revive him but he passed away. The lifeguard should be more experienced in these matters
