Oh and Jake, While I understand your point, when last did you see a vending machine swimming just below the surface, looking for food ?

OK, Ok....so vending machines don't have teeth or a preditorial disposition. I suppose that does make for a different feel for the situation. :-)
On that note, however, I once gave surfing a shot. However, having been bumped by a 5 to 6 foot shark once in shoulder deep water, I have a hard time not thinking about that while bobbing in the water like a fishing cork.
