1. A board for use on snow, the board comprising:

  • (a) a longitudinally extending structural, flexing body;

    (b) a piezoelectric material coupled to the body so as to flex when the body flexes and including a signal generating piece of piezoelectric material to produce an electrical signal in response to a vibration produced within the body; and

    (c) a control circuit electrically connected to the piezoelectric material that receives and regulates the electrical signal produced by the signal generating piece of the piezoelectric material to influence the deformation of a responsive piece of piezoelectric material included in the piezoelectric material to dampen flexing of the body.
