Episode #408 "Road To Nowhere"

When they receive invitations to their class reunion, Grace and Nadine remember a high school road trip they took to an Earth, Wind and Fire concert, and Grace convinces Nadine they should do it again because Earth, Wind and Fire are doing a concert in St. Louis. They borrow Floyd's pharmacy van and take off, but a very pregnant Nadine feels miserable and thinks the trip was a terrible idea, but Grace is determined to have an adventure. When they're pulled over by the police for speeding and Nadine finds that Floyd left some drugs in the van, they think they're in big trouble, but an amused police officer waves them on even though Grace tries to convince him they're a menace to society. In the parking lot at the concert Nadine says she's had it and they give their tickets away, but they get to have their adventure when they encounter the members of Earth, Wind and Fire in the lounge of their hotel.
