i love to surf.
[{"role": "system", "content": "Surfing is a surface water sport in which the wave rider, referred to as a surfer, rides on the forward or deep face of a moving wave, which is usually carrying the surfer towards the shore. Waves suitable for surfing are primarily found in the ocean, but can also be found in lakes or in rivers in the form of a standing wave or tidal bore. However, surfers can also utilize artificial waves such as those from boat wakes and the waves created in artificial wave pools. The term \"surfing\" refers to the act of riding a wave, regardless of whether the wave is ridden with a board or without a board, and regardless of the stance used. The native peoples of the Pacific, for instance, surfed waves on alaia, paipo, and other such craft, and did so on their belly and knees. The modern-day definition of surfing, however, most often refers to a surfer riding a wave standing up on a surfboard; this is also referred to as stand-up surfing. Another prominent form of surfing is body boarding, when a surfer rides a wave on a bodyboard, either lying on their belly, drop knee, or sometimes even standing up on a body board. Other types of surfing include knee boarding, surf matting (riding inflatable mats), and using foils.\n"}, {"role": "assistant", "content": "I did not realize that certain lakes can produce waves that are suitable for surfing!"}, {"role": "user", "content": "That is very interesting. I did not know that either. Where are these lakes?"}, {"role": "assistant", "content": "Apparently it happens where there are standing waves or tidal bores and can happen in any river or lake."}, {"role": "user", "content": "I wonder how often a typical lake has that."}, {"role": "assistant", "content": "It seems that although it can happen in any river/lake, that it is kinda rare - usually in areas that involve incoming tides into a narrow river or a lake via a bay."}, {"role": "user", "content": "Oh okay. That makes sense. I wonder how predictable it is."}, {"role": "assistant", "content": "It seems there are some places where it's more predictable than others, but it's still pretty much a sudden increase in the water level that causes it."}, {"role": "user", "content": "Thanks for the info!"}]
