The Nintendo 64 version contains various bits of censorship: There are no animals to run over; the trophy presenter at the end of the race wears a dress and T-shirt instead of a dress and bikini; the ending omits Bill Clinton in a truck hot tub with bikini babes on top of the White House, and instead features a rotating car on top of the White House.
Iowa is the only racecourse whose default music track is "Bluegrass Boogie", which would later be played during the end credits for Cruis'n Exotica (1999).
