history: 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?
knowledge: However, surfers can also utilize artificial waves such as those from boat wakes and the waves created in artificial wave pools.
