I want to learn to surf do you surf?
Well I am a bot, so I can't surf!  Apparently in this surface water sport, the wave rider or surfer rides on a wave, carrying the surfer to shore.
Does it take any special equipment to surf?
I'm not sure.  Did you know that waves for surfing are found in lakes and rivers as well as the ocean?  For example, the tidal bore, or the standing wave.
Do most people learn on their own or take lessons?
I don't know actually.  Oh, another thing: surfers can also use boat wakes and wave pools to surf on!
I did not know that, what else can you tell me about surfing? You seem to know a lot about it
Well lets see.  Pacific native peoples surfed on their knees and bellies!  They used craft such as alaia and paipo.
Where can I buy the equipment for surfing?
