I've told this story to non-surfers and usually they don't get it. So it goes like this. Was surfing at the Folly Beach pier with 3 to 4 foot waves in super muddy water. I know that it's all sand under me because I've been there so many times. About half a dozen other surfers with me, I ride a smaller board than most 5'3" so I sit on the inside and off to the side of the pack, nobody looking behind me. So there I was sitting on top of my board in 5 to 6 feet of water and suddenly it was like the bottom of the ocean rose up from under me, like I could stand up in super shallow water but I know for a fact that it was to deep for that. Just then the set waves rolled in and the hole pack including myself started to move. I was kind of of shocked and in disbelieve at the time so I continued surfing and didn't say anything.
