how does it make no sense? You said longboarding wasn't skateboarding you said dancing on a skateboard wasn't skateboarding, just wanted to see where you'd draw the line.
But yeah i've seen his stuff, like this one :
You do realize choreographed dance routines were huge in freestyle in the 70's just one of the poplular phases in skateboarding, it wasn't until guys like Mullen who started really pushing trick wise that the dance routines faded from the mainstream. Then mullens form of freestyle faded out and shaped how street skating is today. How is one trend, or one step in skateboarding's evolution less "skateboarding" than another?
