Goddam....talk about brown trousers material.....
I was out late this afternoon after work and had something hit my board from underneath so hard that it actually launched the board off the water

When I looked back, all I could see was a *very* large, dark shape just under the surface....needless to say I vacated the scene rather precipitously

I've been checked out, up close and personal, a few times now by various marine creatures, but that's the first time I've actually hit/been hit by one.
