I don't mind falling but catching an edge is no fun! If you can straight line a run on a slight edge and get up to 50-70 MPH why bother riding with your board completely flat based? I guess I just don't see the need unless your hitting features in the park or landing. I've done it but it's sketchy, I personally get more courage around a .05 B.A.C.
Powder is obviously a different animal.
But it's all fun if you can take the abuse!
