Ive been surfing a whole lot lately. Riding on the surface of a wave feels really great. I ride right up towards the shore.
I've never been able to surf. But I can use a boogie board.
That is somewhat similar to surfing. I have actually surfed on lakes and rivers before on the waves produced by a tidal bore.
I've never seen anyone surf on a lake or a river.
Surfers have to use artificial wake while on lakes and rivers. You can even use the wake of a boat.
That seems way more difficult then ocean surfing.
Its much different, true. Surfing means the act of riding a wave. It is a very general term regardless of stance with or without a board.
