I’m sure entry fees have a lot to do with someone coming from the sprint or the mud ranks over to roadracing. Funny thing is that people are willing to pay good money to watch a auto race on a premier road circuit yet they cringe at spending a bit more to get a chance to actually drive on that same premier road circuit. Go figure.
From a photographers perspective, you’ll never see a good photo of a racer with a camera attached to his head. From a drivers perspective, I’m not willing to take a camera in the throat at 90 mph because you want film of yourself. Keep the Velcro on your shoes, please.
