>>2716599I've shot at the 12 hours of sebring a few times (which I definitely recommend, lots of good spots to shoot from without credentials). advice:
show up a few days early for all of the practice sessions and qualifying. this will give you way more opportunities and also let you scout out good spots.
get a paddock pass or whatever will get you the most access.
lower level racing leagues and lower level tracks will generally give you more access; shooting anything at all F1 is impossible without press credentials, but local level sprint cars you can go wherever, shoot anything.
