-SCCA Club (amateur racing, trophies/medals although some $, usually contingency, some of it from the auto manufacturer)
-SCCA Pro Racing / Trans Am (professional racing, trophies and $$$$ to 7th from what I recall)
-NASCAR (I know, I know, some folks wouldn't call it professional racing, but it is!
)Would a LEO know the difference? Never got wanded / checked going in as a racer, different experience going through spectator entrances though.
