When i was njh in march of this year i asked my doctor there if the ocean was bad for mac. She said mac is everywhere and no one place is worst than others. We should be able to enjoy our lives. We just need to be careful. We go to florida in the winter and i don’t feel any different than i do here in asheville. I live surrounded by forest. I feel that is worst than the ocean. I love walking on the beach and breathing the air. The ocean calms me and its so peaceful. Go and enjoy it!😎
