Frustration

I'm getting really annoyed that I can't seem to achieve the art of 'panning'.
I've photographed moving cars, people, animals, leaves and so forth and I just cannot manage it. Sigh!!

Here is the best shot of a bad, bad bunch. In the original cool, blue form (accidental tungsten white balance) and also in black&white.


If anyone has any tips on panning they will be greatly received.
