I was almost eaten by a shark!

So I wasn't actually almost eaten by a shark, the shark didn't really seem to care about my existence one way or the other, but I was in the water with a shark. Devin and I went to Sea Gull Park which is the beach we saw a shark before. The water was really calm and clear and as I was wading out in thigh deep water I was thinking, "wow, the water is so clear that if there was a shark I could totally see it" and then in front of me to my left was a shark. It looked about 4 feet long and was probably 20 - 30 feet away. I ran out of the water squealing like a girl and then grabbed my camera. I trotted along the shore as it swam north and also warned some other swimmers about the shark heading there way. Sadly, I forgot to put my XD card back in my camera the last time I downloaded pictures and I only had the memory on the camera so I only have one picture where you can vaguely see a shadow in the water. I promise it's a shark and it scared the crap out of me.
