I want to ask Ed Templeton if he could fathom people doing waist high impossibles when he was scooping them around in the 90's.
Look at Dylan Rieder's over a frekkin fence...
He does a mean one in the Gravis clip (along with a dew other impossible variations) over a bench and a tailgrab one which made the cover of The Skateboard Mag.
Plus Dill made a sick one in the previous post.
I can only imagine the impossible becoming more common in the near future.
