Harry Parsons made the sparks fly on his run after seeding 4th in juniors. Unfortunately those sparks were literal and not the figure of speech that would imply a better outcome than what you see here.
One of the coolest Mtb action shots I've ever seen. His bike is obviously beyond his control at this moment but his brain hasn't yet registered that. His form is still on. Focus is straight through the exit of the turn, body leaning the bike, index fingers hovering over the brake levers. Perfect riding form. Except that his bike is horizontal leaning into nothing. He hasn't even registered the pedal strike yet! How in the hell did you capture this Dave? You literally caught the moment of the synaptic gap in his nervous system. Incredible.
