I think it's a great shot. wouldn't it be great if you had had time to think, paln, rehearse and make the shot perfect by adding movement (slower shutter). But it's a miracle you got it at all. Well done.
As a Harley rider I don't recall Rolling thunder...in August?? However....as a Harley rider I guss you could call anytime 'rolling thunder'. The shot is nice no matter when it was taken. Score 7 Justine
Great shot... too bad its blurred by camera motion. More daylight and a faster shutter speed would would solve this... although, sometimes the best shots don't come to us at optimal times ;) -7
