"This road would definitely be an E ride at Disneyland." From 1959 to 1982 the rides were rated from A (teacup kiddie rides) to E (Matterhorn or Pirates of the Caribbean). You bought coupons of differing values and those were your tickets to ride.
There is no opening gambit for this episode.
A bit of Star Trek DS9. Nana Visitor and music from Dennis Mc Carthy.
