I was fishing in the pocket off 15th street on Bolivar Penn. about 30 before sundown, when my leg was nailed by something big and fast. It felt like I was kicked in the wade booty, and kicked hard. As I screamed like you know what, I felt it brush by my other leg, and this was followed by a tail thrash behind me. I did not see the tail just heard it. Then I hauled arse towards the shore amidts all the tubulent water. Would a shark headbut the back of my foot without taking a nip? Do porpoise do this. It could not have been a large red, it just hit to hard. Has this happened to anyone else? Do you know what it was?
