Gone over the falls a few times - once I landed with my fin a few inches from my groin...
The one that sticks out though is when I was a beginner and paddled out into surf way bigger than I had any business with (especially since the water was rough and nasty). Anywho, I was paddling out and I saw a big one coming right at me. I paddled as hard as I could but there was no way to make it. I decided to attempt a duck dive (which I sucked at) but didnt go deep enough. The lip landed right on top of me and I went through a nasty spin cycle. When I came up, my leash had snapped and my board was floating towards shore. The current was pretty strong but I somehow made it in and decided to sit out the rest of the day.
