The taller they are...

I keep telling people that you have lots of time to think about how you're going to contact the ground when you fall off the tall bike.  It was bound to happen, too.  I mean, I was trying to wheelie it...  and I don't do wheelies all that well on small bikes.

But the will to avoid serious injury is a strong one...

As stompaz around the world observe daily, there is always time to tuck and roll! 
(and ripping the SZ vest of doomdom is of course, unthinkable)
