I've alway been terrified of sharks, growing up in the bay area there was always at least one attack every year. Some Fatal some not, but every time I've been out there surfing if I get a feeling I will pull my feet out the water and paddle quickly. If i see a fin I will catch a wave in, unless they're dolphins. Gotta love some dolphins!
This summer though I will try and get my PADI and check out a shark or two.
