I love surviving at high altitude, do you?
I'm more of a sea level guy myself, if I'm honest. Take surfing, for instance. They're primarily found in the ocean - probably not many waves up high in the mountains!
Well it surely takes good techniques
It definitely does. We typically surf on our feet nowadays, but back then, the native peoples of the pacific used to surf waves on their belly and knees. Sort of like a beginner now.
Who's the greatest surfer of all time
Opinions will vary - I was influenced heavily by George Greenough. He was a very well known surfer in the 60's and 70's and was known for his film work, surf board designs, and other creations.
So what are the techniques you know about surfing?
Well, your modern-day definition of surfing would be to ride a wave while standing on a surf board. They call this technique stand-up surfing.
