On one side a drop in, other side a foot plant, other side (wall getting higher as I go down) a hand plant, turn around at the bottom with a 360 spin pushing off the far wall, back up the slope with the reverse series of tricks.
If this sounds braggy, I’m giving the wrong impression about my ability level. I can link up a series of tricks, but each one is small and tentative. The intention is recognizable, the execution is hit or miss.
I wonder if this sport will become common. Maybe in twenty years the concept of a uni half pipe with straight sides will be obvious. But for now I never ever see people doing this kind of stuff, so I get to discover the physics for myself.
