        Joe ,    think about the distance involved... 650ft....     Thats a
little over two football fields.
  Now think about looking for a ball bearing at that distance.. even with a
scope!!! I think a drop of
water on a blade of grass at that distance might be mistaken for the ball
bearing, if the sun hit it just
right... R  Jocoy
