This is 15MB exe file - a cockpit view video (continuous) loop of Cadwell circuit as ridden by BSB rider. Originally sent to me by Rockhopper (ta mate). It's worth a look - sorry if you're on dial-up.
In the video there is a little map in the corner that indicates where you are and also the gear/speed at the time. He gets up to 165mph on the Park Straight whereas I usually manage a bit less than that!
