My dad sent me a link to a You Tube(R) video, which contains footage of this guy doing bike tricks all over in Germany. My dad's response was "THIS GUY HAS TO BE NUTS" written in large size script.
I watched it and then replied, "I LOVED it!!!! He takes "The world is your playground" literally! :-D"
Here is the link so that you too can watch it and then decide for yourself. o;->
