If you place two skis at an angle to each
other, they cannot run straight, but must begin to turn until
they reach a state of equilibrium.

Now wait, a second ... I didn't get too far, but: that's not right. I can do
a wedge straight down the fall line all day (or at least until my legs get
tired and my hips get sore). I can do a wedge in a straight line across the
fall line too.
