Thanks for the comments everyone.
Best part about shooting this form of mototrsport is there is always something visually spectacular occuring so as far as planning goes it's a matter of identifying and getting to the spots with best "potential" and then hoping you can catch it unfolding. Rely on a couple of astute cohorts for this part.
My dunny door station wagon would struggle to get to some of the locations but then hoofing it plays a big part also.
Walter - You probably need to speak to John Thomas. He and others have used of adjectives in relation to myself however I can guarantee Doyen is not one of them. I defer to your opinion though......
