Mid-Life Crisis or Mid-Life Renaissance?

I prefer to think of it as a Mid-Life Renaissance.  At the young age of 49, I have purchased a RipStik.  You can see what they are here.  I got a great deal on a red one at Amazon (I don't know why the red one was cheaper, but it was).

Here's what it looks like:

Basically, it is very much like a skateboard, except instead of having four wheels, it only has two.  This enables you to power the board without pushing your foot on the ground like you do with a regular skateboard.  Instead, you use a back and forth hip motion to make the board pick up speed.  I have no idea how I'm going to learn to ride this thing, but I know that I am.  I will report back with video when I can do it.
