Morgan City Louisiana contains the most helipads of any location in the United States.  This scenery is Petroleum Helicopter International's heliport near Lake Palourde in Morgan City. 7LS3 represents the largest civilian heliport in the United States.   It services the oil rigs in the Gulf of Mexico.  Fly 316 degrees into the gulf and be prepared to encourter hundreds of oil rigs placed by MSFS in the scenery.  None of the gulf rigs have landable helipads at this time.
