Twice I saw an image I believe was on hole #3 on Kiawah that was red within the sea grape bushes just behind the green. It was about 4 foot tall and I thought it looked like someone with a red shirt on but the bush was too thick to make out. Although I've seen sprinkler system mains that high on the course I worked on when I was around 18 but that was more camouflaged (Green) with the scenery so it was not an eye sore to the golfers.
Forgot to mention the sounds I heard 3 times on different occasions while shooting from the fairway. It was the sound of someone striking a ball from a tee somewhere from another hole. I had my speakers up pretty high when it happened. I was just ready to take a shot from the fairway to the green when I heard it Freaked me out totally when it happened because It was totally quite while I was playing a single round.
