The Evo was well and truly wedged. The log he's up against is was about 20ft long and 2ft round and he managed to shift it quite far.
I think there were some arena stages, not sure where they were.
The bloke fishing is my mate Colin, the cold weather makes you do some weird things!
As for the exposure nightmare, couldn't have put it better myself. Shooting motorsport with flash is a bit weird, it's not something I do (very often).
I set the camera to manual, chose a shutter speed, ISO and aperture similar to what the camera might do in Shutter Priority mode and played around with my Speedlite 430, ended up shooting on 1/4 power - seemed to work ok. The only difficult thing is knowing where to point the camera and what to focus on.
