Have you ever been surfing? I tried it once. It's a surface sport where you ride on a moving wave on a board.
Surfing is a fun sort! Ice surfing I suppose
I've never heard of ice surfing. What's that all about? Sometimes surfers can use artificial waves from wave pools.
Don't know much about it though,but I'm sure you have the info 
No I don't know anything about it. However I've also been body boarding which is like surfing but surfers are lying on their belly to ride the waves.
Sure! That's a great sporting activity
In the history of surfing, scientists imagine that riding waves has probably existed ever since humans began swimming in the ocean. I wonder what they used to ride on!
That's really interesting, do you surf?
