I winced each time he put that blade on concrete! I'm sure it's an old one, but just can't look at it closely enough!!
But to the main point. It is impressive what they can do. His spin attempt makes me feel better!! On my pics I also feel the wheels slip out from under me, so I'm comforted to hear them say it.
I wish there was a good parking lot within a Km of my house
But our street was recently re-paved so has as good a surface as anything. Will have to get out there.
