Just spoke with a lady at Dreher Island. She said the primitive area is for youth groups only. She said we could stay in the regular tent area and that there are pictures of each site online so we could see which ones have plenty of trees. It seems to me as I have spoken with several state parks, that each have their own interpretation and policies regarding the primitive areas and using the bathrooms/showers. Hopefully, as hammock camping grows and groups such as ours leave good impressions, more doors will be opened to us in the future.
