This the area?
Well, sort of. In the late 1970’s I would take off from McEntire ANGB. The whole state was local flying area so no flight plan necessary. I would fly either to Hunter AAF or Charleston Muni or Myrtle Beach FBO, refuel, then fly along the SC coast. The route in any case was a large triangle headed back to McEntire.
This to maintain minimums. I took photos, landed on wet beach to collect seashells, chased wild hogs in the salt marshes, & even landed at a seafood processing dock to go in & buy shrimp (OK if for personal use only). ATC knew where I was at all times.
